In a weight-lifting competition, the average (arithmetic mean) of Tom's two lifts was 375 pounds. If twice the weight of his first lift was 300 more pounds than the weight of his second lift, what is the weight, in pounds of his first lift?

A. 225
B. 300
C. 350
D. 372
E. 450

The average of F, first and second, S, lifts was 375 pounds

\(\frac{F + S}{2}=375\)
\(F + S = 750\)

Twice the weight of his first lift was 300 more pounds than the weight of his second lift
\(2F = S + 300\)
\(S = 2F - 300\)

\(F + S = 750\)
\(F + 2F - 300 = 750\)
\(3F = 1050\)
\(F = 350\)

Answer

Using the answer choices on this question would be fast, too, I think.
