Here we have , Jack’s new truck costs $325 per month for car payments. In addition, he estimates that gas and maintenance expenses cost $0.23 per mile. We need to find :

a. Express the monthly cost as a function of the miles driven.

Let number of miles driven be x , & monthly cost be y So , equation is :

⇒ $y=0.23x+325$ , Where 325 is Jack’s new truck costs $325 per month for car payments .

b. How much will Jack have to pay if he drives 1,248 miles in one particular month?

According to question we have ,

$x=1,248$

Putting value of x in $y=0.23x+325$ we get:

⇒ $y=0.23x+325$

⇒ $y=0.23(1248)+325$

⇒ $y=287.04+325$

⇒ $y=612.04\$

Therefore , $612.04 will Jack have to pay if he drives 1,248 miles in one particular month .
