A hardware store sold 10 graphics cards, 14 hard drives, 8 CPUs, and 4 pairs of RAM in one week. The graphics cards cost $600 each, hard drives cost $80 each, CPUs cost $200 each, and RAM cost $60 for each pair. How much money did the store earn this week? Let's be accurate as possible.
It earned 10 * 600 = 6000 dollars by selling graphics cards. It earned 14 * 80 = 1120 dollars by selling hard drives. It earned 8 * 200 = 1600 dollars by selling CPUs. It earned 4 * 60 = 240 dollars by selling RAM. Overall it earned 6000 + 1120 + 1600 + 240 = 8960 dollars this week.
The answer: 8960.
