1. A person worked 3 hours and earned $18,000. How much will he earn working 8 hours? a) $48,000 b) $52,000 c) $56,000 d) $60,000

To find the person's earnings for 8 hours of work, we can set up a proportion based on the given information. We know that the person earned $18,000 for 3 hours of work. Let's call the earnings for 8 hours x. We can set up the proportion: 3 hours / $18,000 = 8 hours / x To find x, we can cross-multiply and solve for it: 3x = 8 * $18,000 3x = $144,000 x = $144,000 / 3 x = $48,000 Therefore, the person will earn $48,000 for 8 hours of work. The correct option is a) $48,000.
