Q: Micah bought envelopes to send, and depending on the weight of the envelope he will need more stamps. If an envelope weighs more than 5 pounds, he will need 5 stamps. If it weighs less than that, it will only need 2 stamps. If he bought 52 stamps with 6 envelopes that weigh less than 5 pounds, how many envelopes in total did Micah need to buy?
A: Micah had to buy 6 * 2 = 12 stamps for 6 envelopes less than 5 pounds. He has 52 - 12 = 40 more stamps to buy. There are 40 / 5 = 8 envelopes that weigh more than 5 pounds. Micah needed to buy 8 + 6 = 14 envelopes. The answer is 14.

Q: Joey needs to take a new prescription. The first day he needs to take one pill. Each day he must take two more pills than the previous day. How many pills will he take in a week?
A: For the second day he takes 1 + 2 = 3 pills. For the third day he takes 3 + 2 = 5 pills. For the fourth day he takes 5 + 2 = 7 pills. For the fifth day he takes 7 + 2 = 9 pills. For the sixth day he takes 9 + 2 = 11 pills. For the seventh day he takes 11 + 2 = 13 pills. For the entire week he takes a total of 1 + 3 + 5 + 7 + 9 + 11 + 13 = 49 pills. The answer is 49.

Q: Jake is from a conservative household so during lunch at school one day, he gave one-quarter of his feeding allowance to a hungry friend. If candies cost 20 cents apiece and Jake's feeding allowance is $4, how many candies can his friend purchase with the money Jake gave to him?
A:
One quarter of $4 is (1 / 4) * $4 = $1. $1 is equivalent to 100 cents. 20 cents will buy 1 candy so 100 cents will buy 100 / 20 = 5 candies. The answer is 5.
