You want to buy a car and you've decided to pay cash instead of taking a loan. The car you want to buy is $6,000. You have already saved $1,300. If your job pays $18 per hour, then how many more hours will you need to work to buy the car?

What is missing from this equation:

_____________________ = 6000

• h + 1300

• h - 1300

• 1300 + 18h

• 1300 - 18h

Answer explanation

1300 + 18h = 6000 is the best equation. The total you need to have is 6000. The amount of money that you have is 1300 (what you saved) plus 18 x hours worked.
