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

Well, Olivia already has got her $8, so we know that the formula will have $ 8+ \ ... $

if she doesnt have AT LEAST $\geq$ $36, then she cannot get the coat. Therefore the right answer is   $ 8 + 7n \geq 36   $   where she must work AT LEAST 4 hours  $ n \geq 4  $
