Question

AJ needs $800. So far, he has saved $290. If his job pays him $12 per hour, write and solve an inequality that can be used to determine the minimum number of hours that he needs to work in order to have enough money for the computer.

Answer 1

800 - 290 = 510. 510 = 12h

Explanation:

$800 is the amount he is trying to save.

$290 is the amount he has so far.

$800 - $290 = $510.

$510 is the amount more he needs to earn.

12h.

12 represents the amount he is paid every 1 hour

H represents the hours he works.

Answer 2

The minimum number of hours is 43.

Explanation:

Total money required = $ 800

Saved money = $ 290

Per hour income = $ 12

Let the number of hours be n.

According to the question

`290 + 12n \geqslant 800\\\\12 n \geqslant 510\\\\n\geqslant 42.5`

So, the minimum number of hours is 43.
