Question

Janie has 3$. She earns 1.50$ for each chore. She wants to earn enough to buy a cd for 13.50$

Answer 1

$1.50x + 3 = 13.50$

If x=number of chores, then you can solve for x to see how many chores Jane would have to do in order to earn enough money for her cd.

Answer 2

1.50x+3=13.50
subtract 3 from both sides
1.50x=10.50
divide both sides by 1.50
x=7
