For this case, the first thing we must do is define a variable.
We have then:
x: number of miles.
By the time the company earns at least $ 100 we have the following inequality:
\(0.19x + 75 \geq100
\)
From here, we clear the value of x.
We have then:
\(0.19x\geq 100 - 75
\)
\(0.19x\geq25
\)
\(x\geq \frac{25}{0.19}
\)
\(x\geq 132
\)
Answer:
the company must drive to earn at least $ 100 more than or equal to 132 miles
