Bob needs $44 to buy a new pair of pants. He has already been able to save $9 and plans to work as a cook where he can earn $7 per hour. Which inequality shows the minimum number of hours, n, that Bob will have to work as a cook to earn enough to buy the pants? (5 points) a. 9 + 7n ≤ 44, so n ≤ 5

b. 9 + 7n ≥ 44, so n ≥ 5

c. 7n ≥ 44 + 9, so n ≥ 7.8

d. 7n ≤ 44 + 9, so n ≤ 7.8
