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?
Thoughts? Step-by-step reasoning:

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.
Thus, the answer is 14.
