[Question]John makes 6 dozen cookies for a bake sale. He sells each cookie for $1.5 and each cookie costs $0.25 to make. He splits the profit between two charities evenly. How much does each charity get?
[Answer]He makes 6 * 12 = 72 cookies. Each cookie makes a profit of $1.5 - $0.25 = $1.25. So he makes a profit of 72 * $1.25 = $90. That means each charity gets $90 / 2 = $45. The answer is 45.
Q: Corna wants to buy a shirt. The store buys the shirt for $20, but charges 30% for profit. However, the shirt is on sale for 50% off the selling price. What is the price now?
A: First find how much the store makes in profit: $20 * 0.30 = $6 for profit. Then find the regular selling price: $20 + $6 = $26 total price. Then multiply the regular price by the discount to get $26 * 0.50 = $13 for the final price. The answer is 13.
Question: Tommy's home is worth 25% more than he bought it for. He sells it and buys a new house that costs $500,000. If he had to take a loan for the 75% he can't pay, how much did he buy his first house for?
Answer: He paid 25% of the new home price because 100 - 75 = 25. He paid $125,000 towards the new home because 500,000 x .25 = 125,000. Therefore he paid $100,000 for his first home because 125,000 / 1.25 = 100,000. The answer is 100000.
Q: Jamie is a firefighter. One day an emergency call comes in from Mrs. Thompson, an elderly woman whose cat can't get down a 20-foot tree. The last time Jamie rescued a cat, he got it down from a 6-foot tree and had to climb 12 rungs of his ladder. How many rungs does he have to climb this time to get the cat down from the tree?
A:
Jamie needed 12 / 6 = 2 rungs per foot of the tree to save the first cat. To climb a 20 - foot tree, Jamie needs 20 * 2 = 40 rungs. The answer is 40.
