[Question]Arven bought five puppies for a total cost of $800. Three puppies are on sale for $150 each. How much does each of those two other puppies cost if they cost the same?
[Answer]Three puppies on sale cost $150 x 3 = $450. The other two puppies cost $800 - $450 = $350. So, each of those two other puppies cost $350 / 2 = $175. The answer is 175.
Q: Maddie wants to see how much her mom spends on coffee each week. She makes herself 2 cups of coffee per day. Each cup has 1.5 ounces of coffee beans. A bag of coffee costs $8 and contains 10.5 ounces of beans. She uses 1/2 a gallon of milk per week. A gallon of milk costs $4. She doesn't add any sugar to the coffee. How much does she spend on her coffee per week?
A: She uses 3 ounces of beans per day because 2 x 1.5 = 3. She uses 21 ounces of beans per week because 7 x 3 = 21. She buys 2 bags of beans per week because 21 / 10.5 = 2. She spends $16 on the beans per week because 2 x 8 = 16. She spends $2 on the milk per week because 4 x (1 / 2) = 2. She spends $18 per week on her coffee because 16 + 2 = 18. The answer is 18.
Question: Jar A has 28 marbles. Jar B has 12 more marbles than jar A. Jar C has twice as many marbles as jar B. How many marbles are there altogether?
Answer: Jar B has 28 + 12 = 40 marbles. Jar C has 2 x 40 = 80 marbles. Therefore, there are 28 + 40 + 80 = 148 marbles altogether. The answer is 148.
[Question]Audrey's key lime pie calls for 1/4 cup of key lime juice but she likes to double this amount to make it extra tart. Each key lime yields 1 tablespoon of juice. There are 16 tablespoons in 1 cup. How many key limes does Audrey need?
[Answer]Her recipe calls for 1 / 4 cup of juice but she wants to double that so she needs 1 / 4 + 1 / 4 = 1 / 2 cup of lime juice. 16 tablespoons are in 1 cup and she only needs 1 / 2 cup so she needs 16 * .5 = 8 tablespoons of juice. 1 key lime yields 1 tablespoon of juice and she needs 8 tablespoons so she needs 1 * 8 = 8 key limes. The answer is 8.

He has 60 - 20 = 40 kilograms of mangoes left after selling them to the market. Colby sold 1 / 2 x 40 = 20 kilograms of mangoes to the community. Therefore, Colby still has 20x8 = 160 pieces of mangoes. The answer is 160.
