Q: Andy bakes and sells birthday cakes. To make two cakes he spends $12 on ingredients, and $1 on packaging for each cake. Andy sells each cake for $15. How much money does Andy make for each cake?
A: Spending $12 on ingredients for 2 cakes, he spends 12 / 2 = $6 on ingredients per cake. Adding the cost of packaging, he spends 6 + 1 = $7 per cake. Selling each cake for $15, Andy's profit is 15 - 7 = $8 per cake. The answer is 8.
Question: Mark and his sister Chris both leave their house for school at the same time. Mark travels at the same speed as Chris, who walks 3 miles per hour. After walking 3 miles Mark has to turn around and go home because he forgot his lunch. If the distance from their house to the school is 9 miles, how much longer does Mark spend walking than Chris?
Answer: First find the total number of miles Mark walks to get his lunch by multiplying the distance he walks back to the house by 2: 3 miles * 2 = 6 miles. Then find the total distance Mark walks by adding that distance to the distance between the house and the school: 6 miles + 9 miles = 15 miles. Now divide the total distance Mark walks by his speed to find how many hours he spends walking: 15 miles / 3 miles / hour = 5 hours. Now divide the total distance Chris walks by her speed to find the total time she spends walking: 9 miles / 3 miles / hour = 3 hours. Now subtract the time Chris spends walking from the time Mark spends walking to find the difference: 5 hours - 3 hours = 2. The answer is 2.

Q: Central Park had 8 more than half of the number of trash cans as in Veteran's Park. Then one night, someone took half of the trash cans from Central Park and put them in Veteran's Park. If originally there were 24 trash cans in Veteran's Park, how many trash cans are now in Veteran's Park?
A: Half the original number of trash cans in Veteran's Park is 24 / 2 = 12 trash cans. Thus Central Park originally had 8 more than half the number of trash cans as what was originally in Veteran's Park, or 12 + 8 = 20 trash cans. Half of the trash cans from Central Park is 20 / 2 = 10 trash cans. After the addition of the 10 new cans, there are now 24 + 10 = 34 trash cans in Veteran's Park. The answer is 34.
Question: Hannah ran 9 kilometers on Monday. She ran 4816 meters on Wednesday and 2095 meters on Friday. How many meters farther did she run on Monday than Wednesday and Friday combined?
Answer: Wednesday + Friday = 4816 + 2095 = 6911 meters. 9 km = 9000 meters. 9000 - 6911 = 2089 meters. Hannah ran 2089 meters farther on Monday than Wednesday and Friday. The answer is 2089.
Q: Millie, Monica, and Marius are taking subjects for school. Millie takes three more subjects than Marius, who takes 4 subjects more than Monica. If Monica took 10 subjects, how many subjects all take altogether?
A:
If Monica took ten subjects, Marius took 10 + 4 = 14 subjects. Marius and Monica have 14 + 10 = 24 subjects which they've taken. Since Millie is taking three more subjects than Marius, she is taking 14 + 3 = 17 subjects. Together, the three have taken 24 + 17 = 41 subjects. The answer is 41.
