Question

Jimmy needs $42 to buy a pack of comic books. He has saved $18 and plans to work as a babysitter to earn $6 per hour. Which inequality shows the minimum number of hours, n, that Jimmy should work as a babysitter to earn enough to buy a pack of comic books?

Answer 1

6n ≥ 42 + 18, so n ≥ 10
6n ≤ 42 + 18, so n ≤ 10
18 + 6n ≤ 42, so n ≤ 4
18 + 6n ≥ 42, so n ≥ 4

Answer 2

So jimmy needs to have at least $42
That means he \[needs\ge 42\]
