Respuesta :

hello,

In each hour of work, you earn $90. So, we can write this as 90x (x is the time in hours).

You already have $150 in the wallet.

Write an inequality that shows many hours you need to work to earn more than $500

150 + 90x >500

90x > 500 - 150

90x > 350

9x > 35

x > 35/9

x> 3.89 approximately

So, you have to work 4 hours to get some money more than $500.
