Scott wants to make and freeze a large batch of ratatouille. At the farmers' market he buys 5 pounds of eggplants and 4 pounds of zucchini at $2.00 a pound. He needs 4 pounds of tomatoes that are $3.50 a pound. The onions are $1.00 a pound and he needs 3 pounds. Then he needs a pound of basil which is sold for $2.50 per half pound.

Question: If this yields 4 quarts, how much does each quart cost?
Answer: He buys 5 pounds of eggplants and 4 pounds of zucchini so he buys 5+4 = <<5+4=9>>9 pounds of produce
These 9 pounds are $2.00 a pound for a total of 9*2 = $<<9*2=18.00>>18.00
He needs 4 pounds of tomatoes that are $3.50 a pound for a total of 4*3.50 = $<<4*3.50=14.00>>14.00
He needs 3 pounds of onions that are $1.00 a pound so that's 3*1 = $<<3*1=3.00>>3.00
The basil is sold by the half-pound and he needs a full pound so that's 2.50*2 = $<<2.5*2=5.00>>5.00
The eggplants and zucchinis cost $18.00, the tomatoes are $14.00, the onions are $3.00 and the basil is $5.00 for a total of 18+14+3+5 = $<<18+14+3+5=40.00>>40.00
This recipe makes 4 quarts and the total price of the vegetables was $40.00 so each quart costs 40/4 = $10.00

Hugo's mountain has an elevation of 10,000 feet above sea level. Boris' mountain has an elevation that is 2,500 feet shorter than  Hugo's mountain.

Question: If Hugo climbed his mountain 3 times, how many times would Boris need to climb his mountain to have climbed the same number of feet as Hugo?
Answer: Boris' mountain has an elevation 2,500 feet shorter than Hugo's mountain, or 10,000-2,500=<<10000-2500=7500>>7500 feet above sea level.
If Hugo climbed his mountain 3 times, his total climbing distance would be 3*10,000=<<3*10000=30000>>30,000 feet.
To climb a total of 30,000 feet, Boris would need to need to climb his mountain 30,000/7,500=<<30000/7500=4>>4 times.

Mrs. Carlton gives out penalty points whenever her students misbehave. They get 5 points for interrupting, 10 points for insulting their classmates, and 25 points for throwing things. If they get 100 points, they have to go to the office. Jerry already interrupted twice and insulted his classmates 4 times.

Question: How many times can he throw things before he gets sent to the office?
Answer: For interrupting, Jerry got 5 points per interruption * 2 interruptions = <<5*2=10>>10 points
For insulting, he got 10 points per insult * 4 insults = <<10*4=40>>40 points
To get to the 100 limit points, Jerry has 100 points - 10 points - 40 points = <<100-10-40=50>>50 points left
He still has 50 points / 25 points per throw = <<50/25=2>>2 throws

Mrs. Choi purchased a house for $80000. Five years later, she sold it for a 20% profit and got a 5% broker's commission from the original price.

Question: How much did the house sell for?
Answer: The 20% profit amounts to $80 000 x 20/100 = $16 000.
The 5% commission amounts to $80 000 x 5/100 = $4 000.
So the selling price is $80 000+ $16 000 + $4 000 = $100 000.

Elsa gets 500 MB of cell phone data each month.

Question: If she spends 300 MB watching Youtube and 2/5 of what's left on Facebook, how many MB of data does she have left?
Answer: First subtract the 300 MB Elsa spent on YouTube: 500 MB - 300 MB = <<500-300=200>>200 MB.
Then multiply 200 MB by 2/5th to find out how much data Elsa spent on Facebook: 200 MB * 2/5 = <<200*2/5=80>>80 MB.
Finally, subtract the data Elsa spent on Facebook from the 200 MB: 200 MB - 80 MB = <<200-80=120>>120 MB.

Lee is saving up for a new pair of sneakers which cost $90. He already has $15 saved. He plans to sell his old action figures to make the rest.

Question: If he sells 10 action figures and still has $25 left after buying the sneakers how much did he charge per action figure?
Answer: Before buying the shoes he had $115 dollars because 90 + 25 = <<90+25=115>>115
He earned $100 from selling action figures because 115 - 15 = <<115-15=100>>100
He sold them each for $10 because 100 / 10 = <<100/10=10>>10

Janet has 9 cards more than Brenda. Mara has twice as many cards as Janet.

Question: How many cards do they have in all if Mara has 40 cards less than 150?
Answer: Mara has 150 - 40 = <<150-40=110>>110 cards.
Janet has 110/2 = <<110/2=55>>55 cards since Mara has twice as many as Janet.
Brenda has 55 - 9 = <<55-9=46>>46 cards since Janet has 9 cards more than Brenda.
Therefore, they all have 110 + 55 + 46 = <<110+55+46=211>>211 cards.

The bald eagle can dive at a speed of 100 miles per hour, while the peregrine falcon can dive at a speed of twice that of the bald eagle.

Question: Starting from the same treetop, if it takes the bald eagle 30 seconds to dive to the ground, how long,  in seconds, will it take the peregrine falcon to dive the same distance?
Answer: Twice the speed of the bald eagle is 100*2=<<100*2=200>>200 miles per hour.
Let "x" be the time in seconds it takes the peregrine falcon to travel to the ground.
Thus, based on the ratio of their speeds, the following expression is given: x=30*(100/200).
Thus, x=15 seconds.

A blacksmith has 400kg of iron to make horseshoes for neighbouring farms and stables. There are 2 farms nearby, each of which has 2 horses. There are 2 stables nearby which all have 5 horses each. While the blacksmith is crafting, a riding school reaches out and asks for as many horseshoes as possible for their own horses. The blacksmith promises to give them however many horseshoes he has left when he has finished his orders for the farms and stables.

Question: If each horseshoe needs 2kg of iron, how many horses will get new horseshoes at the riding school?
Answer: The blacksmith can create a total of 400kg iron / 2kg iron per horseshoe = <<400/2=200>>200 horseshoes.
The farms need enough horseshoes for 2 farms * 2 horses each = <<2*2=4>>4 horses.
The stables need enough horseshoes for 5 stables * 2 horses each = <<5*2=10>>10 horses.
So in total, the farms and stables have 4 + 10 = <<4+10=14>>14 horses that need horseshoes.
This is a total of 14 horses * 4 horseshoes per horse = <<14*4=56>>56 horseshoes.
This means the blacksmith has 200 total horseshoes – 56 horseshoes for the stables and farms = 144 horseshoes left for the riding school.
The riding school therefore will have enough horseshoes for 144 horseshoes / 4 horseshoes per horse = <<144/4=36>>36 horses.

Answer: 5100 * 7 = <<5100*7=35700>>35,700 pounds
1 ton = <<2000=2000>>2000 pounds
8 * 2000 = <<8*2000=16000>>16000 pounds
35,700 + 16,000 = <<35700+16000=51700>>51,700
Seven white rhinos and 8 black rhinos would weigh 51,700 pounds.

James can make a beret from 3 spools of yarn.

Question: If he has 12 spools of red yarn, 15 spools of black yarn, and 6 spools of blue yarn, how many berets can he make?
Answer: First find the total number of spools of yarn James has: 12 spools + 15 spools + 6 spools = <<12+15+6=33>>33 spools
Then divide that number by the number spools each beret needs: 33 spools / 3 spools/beret = <<33/3=11>>11 berets

Ben's new car cost twice as much as his old car. He sold his old car for $1800 and used that to pay off some of the cost of his new car. He still owes another $2000 on his new car.

Question: How much did his old car cost, in dollars?
Answer: His new car costs 1800+2000=<<1800+2000=3800>>3800 dollars.
His old car cost 3800/2=<<3800/2=1900>>1900 dollars.
