Q: A farmer has three trucks to carry water to his farm. Each truck uses three tanks with a capacity of 150 liters of water. How many liters of water in total can the farmer carry in his trucks?
A: 1 truck uses 3 tanks of 150 liters, so a truck can carry 3 tanks per truck * 150 liters = 450 liters per truck. The total amount of water the 3 trucks carry is 3 trucks * 450 liters per truck = 1350 liters. The answer is 1350.
Question: Melanie is making meatballs for dinner. The recipe calls for breadcrumbs. To make the breadcrumbs Melanie is going to tear 2 slices of bread into smaller pieces and then add them to a blender to grind them into fine crumbs. First she tears the bread slices each in half, then tears those halves in half. How many bread pieces is Melanie going to put into the blender?
Answer: Melanie starts with 1 slice of bread that she tears in half, making 2 halves. She takes both of those halves and tears them each in half, 2 halves x 2 more halves in half = 4 pieces per slice of bread. Melanie is using 2 slices of bread x 4 pieces each = 8 pieces overall to add to the blender. The answer is 8.

Q: Christian and Sue wanted to get a $50.00 bottle of perfume for their mom for her birthday. Christian had $5.00 saved up and Sue had $7.00. Christian then mowed 4 of his neighbors' yards, charging $5.00 each, while Sue walked 6 dogs for her neighbors, charging $2.00 per dog. How much more money will Christian and Sue need to make in order to buy the bottle of perfume for their mom?
A: Christian just mowed 4 yards at $5.00 each so he made 4 * 5 = $20.00. Sue just walked 6 dogs at $2.00 each so she made 6 * 2 = $12.00. Christian had $5.00 saved and just made $20.00 while Sue had $7.00 saved and just made $12.00 so together they had 5 + 20 + 7 + 12 = $44. The perfume cost $50.00 and they had $44.00 so they needed to make 50 - 44 = $6.00 more dollars. The answer is 6.
Question: John decides to install a ramp in his house. He needs to get permits which cost $250. After that, he hires a contractor which costs $150 an hour and the guy works for 3 days at 5 hours per day. He also pays an inspector 80% less to make sure it is OK. How much was the total cost?
Answer: The contractor works for 3 * 5 = 15 hours. That means he charged 150 * 15 = $2250. The inspector charged 2250 * .8 = $1800 less. So the inspector charged 2250 - 1800 = $450. So the total amount charged was 250 + 450 + 2250 = $2950. The answer is 2950.
Q: If I give my brother 2 marbles I will have double his number of marbles, but my friend will have triple the number I do. The total number of marbles we have together is 63. How many marbles do I have?
A:
Let X be the number of marbles I have. If I give my brother 2 marbles, I'll have X - 2 marbles left. And my brother will have (X - 2) / 2 marbles. And my friend will have (X - 2) * 3 left. So the total number of marbles is X - 2 + (X - 2) / 2 + (X - 2) * 3 = 63. (X - 2) * 9 / 2 = 63. X - 2 = 14. X = 16 marbles. The answer is 16.
