Given:

Two companies to rent a truck.

Let the number of miles = m

Let y = the total charge to rent a truck

Company A charge is $83 and allows unlimited mileage.

So, y1 = 83

Company B has an initial fee of $65 in charges an additional $.90 for every mile driven.

So, y2 = 65 + 0.9m

We will find when will company A charge less than Company B

So, y1 < y2

So, the inequality will be as follows:

[tex]83<65+0.9m[/tex]

Solve for m:

[tex]\begin{gathered} 83-65<0.9m \\ 18<0.9m \\ \frac{18}{0.9}20 \end{gathered}[/tex]

So, company A charges less than Company B when the number of miles greater than 20 miles
