Part A:
I have attached the graph of this system of inequalities.
Part B:
Plug in (8,10) into both equations
10 > 3(8) + 10
10 > 24 + 10
10 > 34
This is false!
10 < (-3/4)(8) - 1
10 < (-3)(2) - 1
10 < -6 - 1
10 < -7
This is also false!
So, (8,10) is not included in the solution area for the system.

Answer:
$158.75
Step-by-step explanation:
Given:
The Maple Car Rental Comany charges a flat fee of $45 plus 35 cents per mile
And we have to write a linear equation that gives the total cost in terms of numbers of miles driven then find the total cost if the renter drives 325 miles.
Solution:
Total cost = 35 cents of renter drives in miles + fixed charge of the car
Total cost =
Thus, total cost is $158.75, when the renter drives 325 miles.
