The cost of a large pizza is given by c = 0.50t + 18, where c is the total cost and t is the number of toppings. The cost of a m
Mashutka [201]
The toppings would still cost 0.50 each (since it is just toppings)

The large pizza costs $18 if you do not have any toppings
The medium costs half of the large

The medium costs $9 without any toppings, so your new equation will be:

c = 0.50t + 9

hope this helps
