Question

All plain sandwiches at King’s Sandwiches cost $4.75. If a customer wishes to add toppings to the sandwich, they pay an extra $0.50 per topping. Write a function (equation) describing the cost of a sandwich.

A. C(x) = 4.75 + 0.50x
B. C(x) = 4.75 - 0.50x
C. C(x) = 0.50x - 4.75
D. C(x) = 4.75x

Answer 1

The function describing the cost of a sandwich at King’s Sandwiches with additional toppings is C(x) = 4.75 + 0.50x, where x is the number of toppings.

Step-by-step explanation:

The cost of a plain sandwich at King’s Sandwiches is $4.75. For each topping added at an additional $0.50 per topping, the cost function (equation) describing the total cost of a sandwich with x number of toppings would be C(x) = 4.75 + 0.50x. Hence, the correct function from the given options is A: C(x) = 4.75 + 0.50x.
