A girl makes $18 per hour as a math rotor. Her paycheck is calculated by multiplying by $18 times the number of hours she worked how many hours will she have to work to earn more than $720

x = 5

Step-by-step explanation:

asked "How many hours will she have to work to earn $90?".  (If I'm off track about how the questions ends, let me know.)

This is a proportion or ratio problem. The best way to handle these problems is:

- Set it up as fractions equal to each other.

- Be very careful where you put the x (the unknown)

- Cross-multiply to solve.

So our formula is:

18      90

___ = ___

1        X

When we cross-multiply we get:

18X = 90 x 1

18X = 90

x = 5
