Question

Anh earns $7.75 per hour working after school. He needs at least $290 for a stereo system. Write and solve an inequality that describes how many hours he must work to reach his goal.

Answer 1

Answer:

7.75 x Y $\geq$ 290

Step-by-step explanation:

we can do it backwards

290/7.75

about 37.42

so Y = 37.42 hours or higher

(thx for reminding me to round)

or Y can = 38

Answer 2

Hello!!!

Our equation would be

290= 7.75 x h

H which stands for hours. Our equation can be simplfied to 7.75h

Next we must reverse our equation to work fully our.

290 divided by 7.75 is our final equation.

290 divided by 7.75 gets you 37.419 hours

If we want to average this out it is 37.4 hours, however people are not paid to work a percent of an hour.This means Anh, would have to work a full hour to get paid.

For our final answer, Anh must work 38 hours to make enough money to buy his stero.

I hope this helps & Good Luck.
