Answer 2

The inequality that shows to find hours must he work to buy a video game is 7.5h ≥ $60.

Explanation:

Given : Alex earns $7.50 per hour by working after school.

Let h denotes the number of hours he work.

Then total amount ( in dollars) he earn after working h hours = 7.5h

He should have at least (greater than or equal to) $60 for buying a video game.

i.e.  Total amount ( in dollars) he earn ≥ $60

⇒ 7.5h ≥ $60

Therefore , the inequality that shows to find hours must he work to buy a video game is 7.5h ≥ $60.
