Question

Tanner is ordering a pizza at a restaurant. The cost of a cheese pizza is $8.69, and then it costs $0.30 for each additional topping. Which equation represents the cost in dollars, c, of a pizza from this restaurant with a certain number of additional toppings, t?
A.
c = 8.69 + 0.3t
B.
c = 0.3 - 8.69t
C.
c = 8.69 - 0.3t
D.
c = 0.3 + 8.69t

Answer 1

Answer:

Option A. $c=8.69+0.30t$

Step-by-step explanation:

Let

t ------> the number of additional toppings

c ----> the cost of the pizza in dollars

we know that

The linear equation that represent this situation is

$c=0.30t+8.69$

This is the equation of the line in slope intercept form

where

the slope m is equal to

$m=0.30\frac{\ }{topping}$

the y-intercept  b is equal to

$b=\ 8.69$ -----> the cost of a pizza without topping
