Answer :
Answer:
[tex]C(p)=2.50p[/tex]
Step-by-step explanation:
Let
p------> the number of packages of popcorn
C-----> the total cost of popcorn at the movie
we know that
[tex]C(p)=2.50p[/tex] ------> linear equation that represent the situation
The equation represent a direct variation
The slope m is equal to the constant of proportionality k
so
[tex]m=k=2.50\frac{\$}{package}[/tex]
