Hannah wants to get the highest grade in the class on the upcoming math test. Because she is out sick the day of the test, she learns ahead of time the top scores she has to beat. She finds out that one student got a 95% on the exam. Another student only got 3 wrong out of 40.

Question: How many questions does she have to get right to have the highest score in the class?
Answer: One student got 37 questions right because 40 - 3 = <<40-3=37>>37
This student's proportion right is .925 because 37 / 40 = <<37/40=.925>>.925
This student got a 92.5% because .925 x 100 = <<.925*100=92.5>>92.5
The student got got a 95% got 38 right because 40 x .95 = <<40*.95=38>>38
Hannah must beat the student who got a 38 because 38 > 37
Hannah needs to get 39 questions right because 38 + 1 = <<38+1=39>>39

Jamir and his two friends Sarah and Julien, go to their school's swimming pool to swim. Jamir swims 20 more meters per day than Sarah, who swims twice the distance Julien swims. They go to the swimming pool the whole week, swimming the same distances as before.

Question: If Julien swam 50 meters, what's the combined distance for three of them for the whole week?
Answer: If Julien swam for the whole week, then the total distance in meters that he covered is 50*7 = <<50*7=350>>350 meters
Sarah swam twice the distance covered by Julien, which is 2*50 = <<2*50=100>>100 meters
Sarah's total for the whole week is 100*7 = <<100*7=700>>700 meters
If Jamir swam 20 meters more than Sarah, he covered 100+20 = <<20+100=120>>120 meters
Jamir's total for the whole week is 120*7 = <<120*7=840>>840 meters
The combined distance for all of them is 840+700+350 = <<840+700+350=1890>>1890 meters

Question: If there are 28 chocolates left, how many chocolates were in the box?
Answer: The ones with nuts that they ate was 40% of the box because 80% x .5 = 40%
The ones without nuts that they ate equaled 25% of the box because 50% x .5 = 25%
They ate 65% of the box because 40 + 25 = <<40+25=65>>65
They left 35% of the box because 100 - 65 = <<100-65=35>>35
The box had 80 chocolates because 28 / .35 = <<28/.35=80>>80

Mike and John dined at the Taco Palace restaurant. They each ordered the Taco Grande Plate as their main meal, but Mike also ordered a side salad for $2, a plate of cheesy fries for $4, and a diet cola for $2. As a result, Mike's lunch bill was twice as large as John's bill.

Question: What was the combined total cost, in dollars, of Mike and John's lunch?
Answer: Let "x" be the cost in dollars of the Taco Grande Plate.
Since twice the cost of John's Taco Plate equals the cost of Mike's Taco Plate plus added items, then 2x = x+2+4+2.
Simplifying the equation, we get 2x = x+8.
Subtracting x from each side of the equation, we are left with x=8 dollars as the cost of the Taco Grande Plate.
Thus the combined total cost of Mike and John's lunch is 8+8+2+4+2=<<8+8+2+4+2=24>>24 dollars.
#### 24
Phil started his day with $40. He bought a slice of pizza for $2.75, a soda for $1.50 and a pair of jeans for $11.50.

Question: If he has nothing but quarters left of his original money, how many quarters does he now have?
Answer: The total cost of pizza, soda and jeans is $2.75 + $1.50 + $11.50 = $<<2.75+1.5+11.5=15.75>>15.75
He now has $40 - $15.75 = $<<40-15.75=24.25>>24.25 left.
There are 4 quarters in $1.00 so $24 is equal to 24 x 4 = <<24*4=96>>96 quarters.
25 cents is equal to 1 quarter.
Therefore, Phil has 96 quarters + 1 quarter = <<96+1=97>>97 quarters now.
#### 97
A baker is comparing the day’s sales to his daily average. He usually sells 20 pastries and 10 loaves of bread. Today, he sells 14 pastries and 25 loaves of bread.

Question: If pastries are sold for $2 and loaves of bread are sold for $4, what is the difference, in dollars, between the baker’s daily average and total for today?
Answer: The daily average sales of pastries amounts to 20 pastries * $2/pastry = $<<20*2=40>>40.
The daily average sales of bread amounts to 10 loaves of bread * $4/loaf = $<<10*4=40>>40.
Therefore, the daily average is $40 + $40 = $<<40+40=80>>80.
Today’s sales of pastries amounts to 14 pastries * $2/pastry = $<<14*2=28>>28.
Today’s sales of loaves of bread amounts to 25 loaves of bread * $4/loaf = $<<25*4=100>>100.
Therefore, today’s sales amount to $28 + $100 = $<<28+100=128>>128.
This means the total difference between today’s sales and the daily average is $128 – $80 = $<<128-80=48>>48.

The mayor commissioned two artists to paint 50 murals around the city. Once the work was completed, Celina was paid $1,000 more than 4 times the amount Diego got.

Question: If the mayor paid the two a total of $50,000, how much did Diego get?
Answer: Let d be Diego’s payment
Both artists were paid (1000 + 4 * d ) + d = 50000 dollars
This means that 5d = (50000 - 1000) dollars
Therefore Diego was paid d = 49000 / 5 = <<49000/5=9800>>9800 dollars

Paul needed to buy some new clothes for work. He had a 10% off coupon that he could use on his entire purchase after any other discounts. Paul bought 4 dress shirts at $15.00 apiece, 2 pairs of pants that each cost $40.00. He found a suit for $150.00 and 2 sweaters for $30.00 each. When he got to the register, the clerk told him that the store was offering 20% off of everything in the store.

Question: After the discounts and the coupon, how much did Paul spend on his new clothes?
Answer: 4 dress shirts cost $15.00 each so 4*15 = $<<4*15=60.00>>60.00
2 pants at $40.00 cost 2*40 = $<<2*40=80.00>>80.00
2 sweaters at $30.00 cost 2*30 = $<<2*30=60.00>>60.00
Add the suit at $150 and the other items the total was 150+60+80+60 = $<<150+60+80+60=350>>350
The store has having a 20% off sale so .20*350 = $<<350*.20=70.00>>70.00 discount
His new total would be 350-70 = $<<350-70=280.00>>280.00
Then add his 10% discount, .10*280= $<<28=28.00>>28.00 additional off
His final total came out to 280-28 = $<<280-28=252.00>>252.00

Nora is selling muffins to raise $120 for an upcoming school trip. She has packaged the muffins in cases. Each case has three packs of muffins. Each pack has four muffins.

Question: If she prices each muffin at two dollars, how many cases of muffins must she sell to raise enough money for the trip?
Answer: If Nora prices each muffin at two dollars, she will sell 1 pack for 2 * 4 = <<1*2*4=8>>8 dollars
Since there are 3 packs to a case, the case will be sold for 3 * 8 = <<3*8=24>>24 dollars
It therefore means that she needs to sell 120/24 = <<120/24=5>>5 cases of muffins.

His chickens produce a dozen eggs a week because 4 x 3 = <<4*3=12>>12
Each week that he has chickens is $1 cheaper than buying eggs because 2 - 1 = <<2-1=1>>1
After 80 weeks his chickens will be paid off because 80 / 1 = <<80/1=80>>80
After 81 weeks the chickens will be cheaper than buying eggs because 80 + 1 = <<80+1=81>>81

Claire has 400 flowers in her garden. One hundred twenty are tulips, and the rest are roses. Eighty of the roses are white, while the rest are red. Each red rose is worth $0.75.

Question: How much will Claire earn if she can sell 1/2 of the total number of red roses?
Answer: Claire has 400 - 120 = <<400-120=280>>280 roses in her garden.
Thus, she has 280 - 80 = <<280-80=200>>200 red roses.
One-half of the red roses is equal to 1/2 x 200 = <<1/2*200=100>>100.
Therefore, Claire will earn $0.75 x 100 = $75 if she can sell 1/2 of the total number of red roses.
