Question 6 • EAP-Algebra I A

Harrison mows lawns and rakes leaves for his summer and fall weekend jobs. He gets $10 an hour to mow lawns and $8 an hour to rake leaves. If, during September, Harrison mows for m hours and rakes for 12 hours, which expression represents the amount of money he makes? | Harrison mows lawns for 11 hours, so m = 11. How much money does he make in September?

Answer
A
10m – 8
B
10m + 8
C
10m – 8(12)
D
10m + 8(12)

Explanation

Harrison earns $10 for each mowing hour, so mowing for m hours brings in 10m dollars. Raking for 12 hours at $8 per hour brings in 8 × 12 = $96. Adding the earnings gives 10m + 8(12), which is choice D. With m = 11, he earns $110 + $96 = $206 in September.
