    Brighthouse charges $120 a month for their basic plan, plus $2.99 for each on demand movie you buy. Write and solve and inequality to find how many on demand movies could you buy if you want your bill to be less than $150 for the month.

    Let x equal to the number room movie rentals per month. Our inequality is:
    120 + 2.99x < 150

    To solve for the number of movies, Add 120 to each side
    2.99x < 30

    Divide each side by 2.99
    x < 10.03, which means 10 since you cannot buy a fraction of a movie
