Question

You need at least $220 to do your Christmas shopping. You already have $70. You earn $7.00 dollars per hour at your after-school job. Write and solve an inequality to show how many hours you should work earn your Christmas money.

Answer 1

$220 - $70 = $150 (still to earn)
150/7 = 21.4285714
This means you’d have to work for 22 hours but you would earn $4 extra ($154 total).
