Question

Jachin is saving to buy a new tablet that costs more than $400. He already has $85 in his piggy bank, and he is able to put $25 in his bank once a week when he gets paid for mowing lawns. The inequality that represents this situation is 25w+85>400, where w represents the number of weeks Jachin makes a deposit into his piggy bank. What does the solution for the inequality mean in relation to this situation?

Answer 1

13 weeks

Explanation:

400 - 85 = 315 (How much more needed)

315 / 25 = 12.6 (Weeks needed)

Round 12.6 up to 13.

Answer 2

The solution is w>12.6. It will take Jachin a minimum of 13 weeks to save enough money to buy the tablet.
