Question 297536
This can be written as a linear equation in the form of y=mx+b

The pizza cost starts at 5.50, this is your y-intercept

You are charged .85 for each topping.  So your slope is $.85t

A. The equation is C = $.85t + $5.50

B. You have 3 toppings so substitute in 3 for t in the equation.
   
   C =.85(3)+ 5.50
   C = $8.05
