1. If Alex can fold 12 napkins in x minutes, how many napkins can he fold in y hours?

  • A.
  • B.
  • C.
  • D.

Correct Answer: C

Explanation:

C Two variables tells you this is a great place to plug in. Let's pick numbers that make the math easy. You can try x = 30 and y = 2. So in 2 hours there are 4 periods of 30 minutes each: 12 × 4 = 48. Alex can fold 48 napkins in 2 hours. 48 is your target. Plugging into your answer choices gives you (C) as the only correct answer.
