Question

Which equation could represent "the total cost of popcorn at the movie that sells for $2.50 each if p packages of popcorn are purchased"?

C(p) = 2.50p
C(p) = 2.50 + p
C(2.50) = p

Answer 1

A

Explanation:

Answer 2

`C(p)=2.50p`

Explanation:

Let

p------> the number of packages of popcorn

C-----> the total cost of popcorn at the movie

we know that

`C(p)=2.50p` ------> linear equation that represent the situation

The equation represent a direct variation

The slope m is equal to the constant of proportionality k

so

`m=k=2.50(\$)/(package)`
