Answer:

D) When 10 movies are streamed in a month; the total price that month is $28.

Explanation:

Using the function definition, put 10 where you find m, then evaluate:

p(10) = 2(10) +8 = 20 +8

p(10) = 28

The function definition tells you this (28) is the price of streaming 10 movies in a month.
