Ricky needs $45 to buy a jacket. he has saved $15 and plans to work as a babysitter to earn $5 per hour. which inequality shows the minimum number of hours, n, that ricky should work as a babysitter to earn enough to buy the jacket? (5 points)

5n ≥ 45 + 15, so n ≥ 12

5n ≤ 45 + 15, so n ≤ 12

15 + 5n ≥ 45, so n ≥ 6

15 + 5n ≤ 45, so n ≤ 6
