Question: There are 10 bags with 30 oranges each on a truck. A total of 50 pieces of oranges are rotten. Thirty pieces of oranges will be kept for making orange juice and the rest will be sold. How many pieces of oranges will be sold?
Answer: There are a total of 10 x 30 = 300 pieces of oranges in a truck. A total of 50 + 30 = 80 pieces of oranges will not be sold. Thus, 300 - 80 = 220 pieces of oranges will be sold. The answer is 220.

Question: Joe sells ham and cheese sandwiches for $1.50. If a slice of bread costs $0.15, a slice of ham costs $0.25 and a slice of cheese costs $0.35, how many cents does a sandwich with one slice of each protein cost Joe to make?
Answer: First find the cost of two slices of bread: $0.15 / slice * 2 slices = $0.30. Then add the cost of one slice each of ham and cheese: $0.30 + $0.25 + $0.35 = $0.90. The answer is 90.

Question: On their way driving to Los Angeles, Benjamin and James see lots of billboard ads. Curious, Benjamin starts to count how many they see. In the first hour once he starts counting he counts 17 billboards. In the second hour once he starts counting he sees 20 billboards. In the third hour he sees 23 billboards. James asks Benjamin the average number of billboards they've seen per hour. What should Benjamin tell him?
Answer: Benjamin counts 17 + 20 + 23 = 60 billboards total on the way to Los Angeles. Benjamin saw those billboards over 3 hours, so the average number of billboards per hour they saw 60 / 3 = 20 billboards per hour. The answer is 20.

Question: Matt is four times as old as Fem. Currently, Fem is 11 years old. In two years, what is the sum of the ages of Matt and Fem?
Answer:
Matt is 11 x 4 = 44 years old now. In 2 years, Matt will be 44 + 2 = 46 years old. In 2 years, Fem will be 11 + 2 = 13 years old. So, the sum of their ages in two years is 46 + 13 = 59 years old. The answer is 59.
