Adam and Tom are brothers. Adam is 8 years old and Tom is 12 years old.

Question: In how many years will their combined age be 44 years old?
Answer: At present, the two brothers have a combined age of 8 + 12 = <<8+12=20>>20 years old.
Therefore, 1 year means an increase in the sum of their ages by 1 * 2 = <<1*2=2>>2 years.
Adam and Tom need a total of 44 - 20 = <<44-20=24>>24 more years to be 44 years old together.
So both brothers will be 44 years old together after 24 / 2 = <<24/2=12>>12 years.

Monica charges $25.00 per person when catering a dinner party. For repeat customers, she offers a 10% discount. Phoebe is a repeat customer who is having a dinner party for 20 guests.

Question: How much will Monica make from the party?
Answer: Phoebe is having 20 guests and Monica charges $25.00 per person so that’s 20*25 = $<<20*25=500.00>>500.00
Phoebe is a repeat customer so she gets 10% off of $500.00 so that’s .10*500 = $<<10*.01*500=50.00>>50.00 discount
Monica is charging $500.00 minus the repeat customer discount of $50.00 so she will make 500-50 = $<<500-50=450.00>>450.00

The total average age of three friends is 40. Jared is ten years older than Hakimi, and Molly's age is 30.

Question: How old is Hakimi?
Answer: The total age for the three friends is 40*3 = <<40*3=120>>120
If Molly's age is 30, then Jared and Hakimi have a total age of 120-30 = 90.
Let's say the age of Hakimi is x.
Since Jared is 10 years older than Hakimi, Jared is x+10 years old.
Jared and Hakimi's total age is x+(x+10) = 90
This translates to 2x=90-10
2x=80
Hakimi's age is x=80/2
This gives us x=<<40=40>>40, which is Hamkimi's age.

Martin rings the small bell 4 times more than 1/3 as often as the big bell.

Question: If he rings both of them a combined total of 52 times, how many times does he ring the big bell?
Answer: Let s be the number of times the small bell rings, and b be the number of times the big bell rings. We know that s + b = 52 and s = 4 + 1/3b.
Substituting the second equation into the first equation, we get 4 + 1/3b + b = 52
Subtracting 4 from both sides, we get 1/3b + b = 48
Combining like terms, we get 4/3b = 48
Dividing both sides of the equation by 4/3, we get b = 36

Apple can run at a rate of 3 miles per hour. Mac can run at a rate of 4 miles per hour.

Question: In minutes, how much faster will Mac run a 24 mile race?
Answer: First find how fast each runs. Apple = 24 miles / 3 miles per hour = <<24/3=8>>8 hours
Mac = 24 miles / 4 miles per hour = <<24/4=6>>6 hours.
Mac runs 8 hours - 6 hours = <<8-6=2>>2 hours faster.
1 hour = 60 minutes, so, Mac runs faster by 2 hours * 60 minutes = <<2*60=120>>120 minutes.

Chrystal’s vehicle speed is 30 miles per hour. Ascending the mountain decreases its speed by fifty percent, and descending the mountain increases its speed by twenty percent.

Question: If the distance going to the top of the mountain is 60 miles and the distance going down to the foot of the mountain is 72 miles, how many hours will Crystal have to pass the whole mountain?
Answer: The vehicle's speed decreases to 30 x 0.50 = <<30*0.50=15>>15 miles per hour when ascending to the top of the mountain.
So, the total time Crystal will have to spend going to the top of the mountain is 60 / 15 = <<60/15=4>>4 hours.
And the speed of the vehicle increases by 30 x 0.20 = <<30*0.20=6>>6 miles per hour when going down to the foot of the mountain.
So, the total speed of the vehicle when going down is 30 + 6 = <<30+6=36>>36 miles per hour.
Thus, Chrystal will have to spend 72 / 36 = <<72/36=2>>2 hours to descend from the mountain.
Therefore, the total hours she will spend to pass the whole mountain is 4 + 2 = <<4+2=6>>6 hours.

Jerry wakes up one morning and finds the thermostat set to 40 degrees. He set it to double the initial temperature. His dad notices, yells at Jerry, and reducing the temperature by 30 degrees. Later, Jerry's mother reduces the temperature by 30%, before his sister increases it by 24 degrees.

Question: What's the final temperature?
Answer: First double the initial temperature: 40 degrees * 2 = <<40*2=80>>80 degrees
Then reduce that amount by 30 to reflect the dad's change: 80 degrees - 30 degrees = <<80-30=50>>50 degrees
Then multiply that number by 30% to find how much Jerry's mother reduces the temperature: 50 degrees * .3 = <<50*.3=15>>15 degrees
Now subtract 15 degrees from 50 degrees to find the temperature after the mother's change: 50 degrees - 15 degrees = <<50-15=35>>35 degrees
Finally, add 24 degrees to find the final temperature: 35 degrees + 24 degrees = <<35+24=59>>59 degrees

Today, he gave rides to three groups, drove for eight hours, and had to put 17 gallons of gas at $3 per gallon in the limo to refill the tank. He got two good reviews.

Question: How many dollars is he owed for his work today?
Answer: Hayden gave 3 groups rides, so he is owed 3 * 5 = $<<3*5=15>>15.
He drove for 8 hours, so he is owed 15 * 8 = $<<15*8=120>>120.
He refilled the gas tank, so he is owed back 17 * 3 = $<<17*3=51>>51.
He got two good reviews for a bonus of 2 * 20 = $<<2*20=40>>40.
Hayden is owned 15 + 120 + 51 + 40 = $<<15+120+51+40=226>>226 for his work today.

Three years from now, Tully will be twice as old as Kate.

Question: How old was Tully a year ago if Kate is now 29 years old?
Answer: Three years from now, Kate will be 29 years + 3 years = <<29+3=32>>32 years old.
So by that time, Tully will be 32 years x 2 = <<32*2=64>>64 years old.
This means, Tully is 64 years - 3 years = <<64-3=61>>61 years old now.
Therefore, Tully was 61 years - 1 year = 60 years old last year.

Bertha plays tennis. Every ten games, one of her tennis balls wears out. Every five games, she loses a ball. Every four games, she buys a canister of three balls. She started with two balls and gave one to her partner.

Question: After twenty games, how many tennis balls does she have?
Answer: Bertha wears out 20 / 10 = <<20/10=2>>2 tennis balls in 20 games.
She loses 20 / 5 = <<20/5=4>>4 tennis balls in 20 games.
She buys canisters of 3 * 20 / 4 = <<3*20/4=15>>15 tennis balls in 20 games.
Bertha started with 2 balls and gave 1 away, so she has 2 + 15 - 2 - 4 - 1 = <<2+15-2-4-1=10>>10 tennis balls after twenty games.

Mark has a really bad headache. He takes 2 Tylenol tablets of 500 mg each and he does every 4 hours for 12 hours.

Question: How many grams of Tylenol does he end up taking?
Answer: He takes 12/4=<<12/4=3>>3 doses
Each dose is 500*2=<<500*2=1000>>1000 mg
So he takes 3*1000=<<3*1000=3000>>3000 mg
So he takes 3000/1000=<<3000/1000=3>>3 grams of Tylenol
