Kayla pays her plumber $22 per hour to replace her drain pipe. She ends up paying him $99. Which equation can you use to find h, the number of hours the plumber worked?

Let's see...
.
FORMULAS!! Or equations too...
.
Sorry, we just have to, even if you don't want to.
.
$22x = $99, where x is the numbers of hours the plumber worked.
.
Now this is REALLY easy.
.
Divide 22 on both sides!!
.
22x/22 = 99/22.
.
So... what's 99/22?
.
4.5.
.
The plumber worked 4.5 hours.
.
Hope I helped!!

Simple....

so, if she payed him $99 in total and she payed him $22 dollars per hour...

just make it...

99=22h
and...


(99)/(22)= (22h)/(22)

4.5=h

Thus, the plumber worked 4.5 hours. (4 and a half hours)
