E. t trucks

A. 4 trucks will make $80 because 4 × 20 = 80, so they need to wash 38 cars to make the other $380 because 38 × 10 = 380.

($80 + $380 = $460)

B. 15 trucks will make $300 because

15 × 20 = 300, so they need to wash 16 cars to make the other $160 because 16 × 10 = 160. ($300 + $160 = $460)

C. 21 trucks will make $420 because

21 × 20 = 420, so they need to wash 4 cars to make the other $40 because 4 × 10 = 40.

($420 + $40 = $460)

D. 27 trucks will make $540, so they won't have to wash any cars because they would have already exceeded their goal of $460.
