    Therefore the price of an foundation drink is $ 3.20 (approx).

    Step-by-step explanation:

    Let the price of one fountain drink be x and one beg of popcorn be y.

    The Clayton family bought 4 fountain drinks and 3 begs of popcorn and paid $22.50. The Hanks family bought 5 fountain drinks and 2 begs of popcorn and paid $23.75.

    According to the problem,

    4x+3y=22.50 ... (1)

    5x+2y=23.75 ... (2)

    Equation (1) * 5 - Equation (2) * 4

    20x+15y - (20x+8y) = 112.5-91

    ⇔20x + 15y - 20 x-8y=21.5

    ⇔7y=21.5

    ⇔y = 3.07

    putting the value of y in equation (1)

    4x+3*3.07 = 22.50

    ⇔4x=22.50 - 9.21

    ⇔x=3.20

    Therefore the price of an foundation drink is $ 3.20 (approx).
