Enrique weighs 5 pounds more than twice Brendan's weight.
If their total weight is 225 pounds, how much does Enrique weigh?

  1. 125 pounds
  2. 152 pounds
  3. 165 pounds
  4. 115 pounds

Answer(s): B

Explanation:

If E + B = 225, and E = 2B + 5, then 225 − B = 2B + 5.
Solving for B:
3B = 220
B = 73.3.
225 − 73.3 = 151.7.
