Olivia needs $36 to buy a coat. She has saved $8 and plans to work as a babysitter to earn $7 per hour. Which inequality shows the minimum number of hours, n, that Olivia should work as a babysitter to earn enough to buy the coat?
8 + 7n ≤ 36, so n ≤ 4
8 + 7n ≥ 36, so n ≥ 4
7n ≥ 36 + 8, so n ≥ 6.3
7n ≤ 36 + 8, so n ≤ 6.3
