Answer the following question.
Every day, Sara bakes 10 cakes and puts them in his refrigerator. He does this for 5 days. Carol then comes over and eats 12 of his cakes. If it takes 2 cans of frosting to frost a single cake, how many cans of frosting does Bob need to frost the remaining cakes?
Step-by-step reasoning process: After 5 days, Sara has baked 5 days * 10 cakes / day = 50 cakes. After Carol's feast, there are 50 cakes - 12 cakes = 38 cakes remaining. Sara needs 2 cans / cake * 38 cakes = 76 cans of frosting.
The answer is 76.

Answer the following question.
A forester is planting trees. The forest already has 30 native trees. On Monday he triples the number of total trees in the forest by planting new trees. On Tuesday, he plants a third of the amount he planted on Monday. How many trees has the forester planted in total?
Step-by-step reasoning process: Let M be the number of trees he plants on Monday. On Monday the forest was three times larger from the trees that were originally there and the M trees: 3 * 30 = 30 + M trees. So, 90 = 30 + M. And, M = 60 trees. On Tuesday, he planted 60 trees / 3 = 20 trees. In total, he has planted 60 trees + 20 trees = 80 trees.
The answer is 80.

Answer the following question.
Harper needs to buy teacher appreciation gifts for her children’s teachers. Her son has 3 different teachers and her daughter has 4. If she spent $70 on gifts, how much did each gift cost?
Step-by-step reasoning process: Her son has 3 teachers and her daughter has 4, so together they have 3 + 4 = 7 teachers. Harper has already spent $70 on 7 gifts, so she spent $70 / 7 = $10 per gift.

Answer the following question.
Tony has two fish. Every year, his parents buy him two more, but one of them dies. How many fish will he have in five years?
Step-by-step reasoning process: Each year Tony has one more fish than before because 2 - 1 = 1. In five years, he will have 5 more fish because 5 x 1 = 5. In five years he will have 7 fish because 2 + 5 = 7.
The answer is 7.
