Answer:
The answer is D.
Step-by-step explanation:
The question has says each burger costs $7.95 and each extra topping costs $1.00. So you can make an expression in terms of c and t where c is the total cost and t is the number of toppings :
c = 7.95 + 1.00t
(You should not put t at 7.95 because 7.95 is the original and fixed value for each burger)
e.g.
Burger with extra cheese + onion,
Let t = 2, (because there are 2 toppings in this burger)
c = 7.95 + 1.00t
c = 7.95 + 1.00(2)
= 7.95 + 2.00
= $ 9.95
