126 dollars / 7 hours of work = 18 dollars per hour (Pretty neat honestly)

So she made 216 dollars / x = 18 dollars per hour

18x=216 (cross multiply)

216/18 = 12 hours of work

Answer: 12 hours

Step-by-step explanation:

It takes her 7 hours to make $126 dollars and we need to find out how many hours(a) to make $216

So this is the equation

7 hours= 126 dollars

a hours= 216 dollars

Cross multiply

126 x a = 7 x 216

126a = 1512

Divide both sides by 126

a= 12 hours
