Question

Santiago makes seven per hour +5 dollars for every delivery he mix how many deliveries will he have to make to earn at least $80 in a five hour workday

Answer 1

Answer: He will have to make at least 9 deliveries.

Explanation:

80 ≤ (7 * 5) + 5d

d = delivery

7 * 5 = 35

80 ≤ 35 + 5d

Subtract 35 from each side

45 ≤ 5d

Divide each side by 5

9 ≤ d
