Question

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?

8 + 9n ≥ 80, so n ≥ 8
8 + 9n ≤ 80, so n ≤ 8
9n ≥ 80 + 8, so n ≥ 9.8
9n ≤ 80 + 8, so n ≤ 9.8

Answer 3

Needs $80.
Saved $8.
Earns $9 per hour.

8 + 9 * hours worked = 80, but since they want an inequality the equal sign will not work.
8 is initial amount of money.

The rest of this question should be simple, enough if you do not understand let me know.

Answer 4

8+9n≥80
