x = number of miles driven
Since $0.19 per mile driven is added, that's + 0.19x
Flat rate of $75 initially, 75 + 0.19x

The inequality is at least $100 which means $100 or more.
75 + 0.19x < 100
0.19x < 25
x < 131.58
x < 132

The driver needs to drive 132 miles to earn at least $100

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:

[tex] 0.19x + 75 \geq100
[/tex]

From here, we clear the value of x.

We have then:

[tex] 0.19x\geq 100 - 75
[/tex]

[tex] 0.19x\geq25
[/tex]

[tex] x\geq \frac{25}{0.19}
[/tex]

[tex] x\geq 132
[/tex]

Answer:

the company must drive to earn at least $ 100 more than or equal to 132 miles
