Question

Isaac is saving for a game system that costs $299. He currently has $75 in his savings account. He gets $40 a week doing yard work for his neighbors.

Which inequality represents the minimum number of weeks he must work to earn enough money to purchase the game system?

5.6 is definitely wrong just a heads up

Answer 1

6 weeks

Explanation:

75 + 40x ≥ 299

40x ≥ 299 - 75

40x ≥ 224

x ≥ 224/40

x ≥ 5.6

Round up to nearest whole week, 6. He won't get paid for a partial week.

He has to work at least 6 weeks to earn enough money to buy the $299 game system
