Given.

Janie has 3$.

Earning per chore=1.20$

Target amount=13.50$

So; She must earn atleast 13.50$ to buy the CD.

No: of chores she does =c

So the inequality becomes as...

3+ c(1.20) ≥ 13.50

=> c(1.20)≥10.50

=> c≥1.5/1.2

=> c≥15/12

=> c≥ 5/4

=> c≥ 1.25

so The required inequality is c≥1.25.

And the Graph will be starting from 1.25(inculded) towards right to infinity.

Hope it helps...
