Answer:
a. The total charge for first restaurant (in dollars) = 16x + 8
The total charge for the second restaurant (in dollars) = 18x
b. 16x+8=18x models the equation when the charge would be same for both restaurants.
Explanation:
Given that:
Delivery charges of first restaurant = $8
Price per pizza = $16
Let,
x be the number of pizzas bought
Total cost = 16x + 8
There are no delivery charges for the second restaurant.
Price per pizza = $18
Total cost = 18x
The charge will be the same when
Total cost of first restaurant = Total cost of second restaurant
16x + 8 = 18x
Hence,
a. The total charge for first restaurant (in dollars) = 16x + 8
The total charge for the second restaurant (in dollars) = 18x
b. 16x+8=18x models the equation when the charge would be same for both restaurants.
