Mr. Renzo owns a company that makes specialized big screen TVs. From 2000 through 2015, the number of TVs produced can be modeled by M (x) = 3x^2-11x+20 where x is number of years since 2000. The average revenue per TV (in dollars) can be modeled by R (x) = 60x+10. Write a polynomial T (x) that can be used to model Mr. Renzo's total revenue

    T (x) = 180x³ - 630x² + 1090x + 200

    Step-by-step explanation:

    The number of TVs produced can be modeled by M (x) = 3x² - 11x + 20, where x is number of years since 2000 The average revenue per TV (in dollars) can be modeled by R (x) = 60x + 10 The total revenue is the product of the revenue per TV and the number of TV

    Total revenue = M (x). R (x)

    ∵ M (x) = 3x² - 11x + 20

    ∵ R (x) = 60x + 10

    ∴ Total revenue = (3x² - 11x + 20) (60x + 10)

    ∵ T (x) can be used to model Mr. Renzo's total revenue

    ∴ T (x) = (3x² - 11x + 20) (60x + 10)

    Let us multiply each term in the 1st bracket by each term in the 2nd bracket, then add the like terms

    (3x² - 11x + 20) (60x + 10) = 3x² (60x) + 3x² (10) + (-11x) (60x) + (-11x) (10) + 20 (60x) + 20 (10)

    (3x² - 11x + 20) (60x + 10) = 180x³ + 30x² + (-660x²) + (-110x) + 1200x + 200

    Remember (-) (+) = (-)

    (3x² - 11x + 20) (60x + 10) = 180x³ + 30x² - 660x² - 110x + 1200x + 200

    Add like terms

    (3x² - 11x + 20) (60x + 10) = 180x³ + (30x² - 660x²) + (-110x + 1200x) + 200

    (3x² - 11x + 20) (60x + 10) = 180x³ - 630x² + 1090x + 200

    ∵ (3x² - 11x + 20) (60x + 10) = 180x³ - 630x² + 1090x + 200

    ∵ T (x) = (3x² - 11x + 20) (60x + 10)

    ∴ T (x) = 180x³ - 630x² + 1090x + 200
