The function y=14.99+1.25x represents the price (y) for a pizza with (x) toppings. Which is not a reasonable value for this function?

A - 14.99

B - 17.49

C - 18.25

D - not here

C

Step-by-step explanation:

because if you input 18.25 into the equation and solve you get and non-whole number of 2.608.

It is impossible to have 2.608 toppings on your pizza, it has to be a whole number.

All the other answers had whole numbers besides C, therefore C is wrong.
