Aone-topping pizza costs $15.00. each additional topping costs $1.25. let x be the number of additional toppings. you have $20 to spend. which equation can you solve to find the number of additional toppings you can get on your pizza?

the choices are:
a. 15x+1.25=20
b. 1.25x+15=20
c. 1.25x-15=20
d. 15x-1.25=20

So,

Our total will be equal to 20.  If we want 1 additional topping, we will have an additional $1.25.  If we want 2 additional toppings, we will have an additional $2.50.  So we can just multiply the number of additional toppings by 1.25 to get the additional amount.

1.25x

However, you will have already spent $15.

1.25x + 15 = 20

This is option B.

P.S. You will be able to put exactly 4 additional toppings.

In this problem it decreased 20%
