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

Option A.
`c=8.69+0.30t`

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(\$)/(topping)`

the y-intercept b is equal to

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