Hermes gets $4 an hour for babysitting. He needs to earn at least $100 for a stereo. Write and solve an inequality to find the number of hours he must babysit to earn enough for the stereo.
100=4
Divide the sides by four
100=4x
Times it by five
And the answer is he will work 25 hours at least ;)
Hope that helped..
And your welcome..;)
