A. 720

B. 660

C. 510

D360

Given:

Tom's earnings: x

Jan's earnings: 2x - 150

Total earnings: 1380

x + 2x - 150 = 1380

3x = 1380 + 150

3x = 1530

3x/3 = 1530/3

x = 510

Tom's earnings: x = 510

Jan's earnings: 2x - 150 = 2 (510) - 150 = 1,020 - 150 = 870

total earnings: 1,380

510 + 870 = 1,380

1,380 = 1,380
