Answer:
the customer would pay $111 after renting the car for 7 additional days.
Explanation:
Let's denote the number of additional days a customer rents the car as "x". We are trying to find the point at which the cost from both rental car companies is the same. Let's set up the equations:
For Donald’s Rentals:
Cost = $48 (for first day) + $9 (for each additional day) * x
For Weston Rent-a-Car:
Cost = $41 (for first day) + $10 (for each additional day beyond the first) * x
Setting these two costs equal to each other and solving for "x" will give us the number of additional days at which the costs are the same:
$48 + $9x = $41 + $10x
Now, let's solve for "x":
$9x - $10x = $41 - $48
-$x = -$7
x = 7
So, after renting the car for 7 additional days, the cost from both companies will be the same. Now let's calculate the cost:
Cost = $48 + $9 * 7 = $48 + $63 = $111
Therefore, the customer would pay $111 after renting the car for 7 additional days.
