Answer:
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
