The answers are:
a. x≈24 hours
b. x≈33.5 hours
c. x≈23.25 hours
The given equation is y=8.76x, where
y represents the total earnings, and
x represents the number of hours worked.
To find the number of hours Crystal worked (x) for a given total earnings (y), you can rearrange the equation as follows:
x=

Now, let's calculate the number of hours worked for each given total earnings:
a. For y = $210.24:
x=
≈24
b. For y = $293.46:
x=
≈33.5
c. For y = $203.67:

x ≈23.25
So, the answers are:
a. x≈24 hours
b. x≈33.5 hours
c. x≈23.25 hours
