Gavin needs $80 to buy a fish tank. He has saved $8 and plans to work as a babysitter to earn $9 per hour.
Which inequality shows the minimum number of hours, n, that Gavin should work as a babysitter to earn
enough to buy the fish tank? (5 points)
O 8 + 9n z 80, so n z 8
8 + 9n s 80, so n ≤ 8
) 9n z 80 + 8, so n z 9.8
O Ins 80 + 8, so n $ 9.8
