Question

The cost of renting movies from an online video store is represented by the equation y = 2x + 4 where x represents the number of months you rent movies. What is the cost of renting 7 movies?

Answer 1

y = $18

Explanation:

Given:

y = 2x + 4

Where,

y = total cost of renting the movie

x = number of movies rented

What is the cost of renting 7 movies?

y = 2x + 4

= 2(7) + 4

= 14 + 4

= 18

y = $18
