Answer:
c)325
Step-by-step explanation:
Let x and y be the weights of first and second lifts, respectively. Then:
x + y = 750 (the total weight of Joe's two lifts was 750 pounds);
2x = y + 300 (twice the weight of his first lift was 300 pounds more than the weight of his second lift);
Solving gives x = 350.
