Answer this question:Mary has 26 blue shirts and 36 brown shirts. If she gives away half of her blue shirts and a third of her brown shirts, how many shirts does she have left?
Mary gives away 26 / 2 = 13 blue shirts. Mary gives away 36 / 3 = 12 brown shirts. Mary has 26 - 13 = 13 blue shirts left. Mary has 36 - 12 = 24 brown shirts left. Mary has 13 + 24 = 37 shirts left.

Answer this question:Antonio is preparing a meal of spaghetti and meatballs for his family. His recipe for meatballs calls for 1/8 of a pound of hamburger per meatball. Antonio has 8 family members, including himself. If he uses 4 pounds of hamburger to make meatballs, and each member of the family eats an equal number of meatballs, how many meatballs will Antonio eat?
If one meatball is made from 1 / 8 pound of hamburger meat, then 4 pounds of hamburger meat will make 4 / (1 / 8) = 4 * 8 = 32 meatballs. 32 meatballs divided amongst 8 family members is 32 / 8 = 4 meatballs per family member.
The answer is 4.

Answer this question:A town is trying to clear litter from its streets. The council pays for adding 14 trash cans to the streets and also pays for adding twice as many trash cans to the back of stores. How many trash cans has the town paid for?
At the back of stores, the town has paid for 14 trash cans on the streets * 2 = 28 trash cans. The town has therefore added 14 trash cans on the streets + 28 trash cans at the back of stores = 42 trash cans.
The answer is 42.

Answer this question:John is laying the foundation for 3 homes. Each home needs a slab of concrete that is 100 feet by 100 feet by .5 feet. Concrete has a density of 150 pounds per cubic foot. A pound of concrete cost $.02 per pound. How much does the foundation cost?
The volume of the slab is 100 * 100 * .5 = 5000 cubic feet. So it weighs 5000 * 150 = 750000 pounds. That means the cost is 750000 * $0.02 = $15,000 per house. So the total cost for all 3 houses is $15000 * 3 = $45,000.
The answer is 45000.
