Q: Kennedy’s car can drive 19 miles per gallon of gas. She was able to drive 15 miles to school, 6 miles to the softball park, 2 miles to a burger restaurant, 4 miles to her friend’s house, and 11 miles home before she ran out of gas. How many gallons of gas did she start with?
A: 2
Step-by-step reasoning process: Kennedy drove 15 + 6 + 2 + 4 + 11 = 38 miles. She gets 19 miles per gallon of gas, so she started with 38 / 19 = 2 gallons of gas.


Q: Ben has 8 apples more than Phillip does. Tom has three eighths as many apples at Ben has. If Phillip has 40 apples, how many apples does Tom have?

Q: 2 tablespoons of popcorn kernels will make 4 cups of popcorn. For movie night, Joanie wants 3 cups of popcorn, Mitchell wants 4 cups of popcorn, Miles and Davis said they would split 6 cups of popcorn and Cliff said he would only eat 3 cups. How many tablespoons of popcorn kernels will they need?
A: 8
Step-by-step reasoning process: If Joanie wants 3 cups, Mitchell wants 4 cups, Miles & Davis want 6 cups and Cliff wants 3 cups then they want 3 + 4 + 6 + 3 = 16 cups of popcorn. Every 2 tablespoons makes 4 cups and they want 16 cups so 16 / 4 = 4 groups of 2 tablespoons are needed. Thus they need 4 * 2 = 8 tablespoons in total.


Q: A library cabinet houses five ancient scrolls. The first scroll is 4080 years old. If each scroll is older than the last by half as many years as the last scroll’s age, how old is the fifth scroll?
A: 20655
Step-by-step reasoning process: The second scroll is 4080 + 4080 / 2 = 4000 + 2040 = 6120 years old. The third scroll is 6120 + 6120 / 2 = 6120 + 3060 = 9180 years old. The fourth scroll is 9180 + 9180 / 2 = 9180 + 4590 = 13770 years old. The fifth scroll is 13770 + 13770 / 2 = 13770 + 6885 = 20655 years old.
