    a) 7 (8) + 9 (12)

    b) 7x+45

    c) 10 hours

    Step-by-step explanation:

    Hi, to answer this question we have to write an expression

    The amount earned by Jason must be equal to the product of the amount he earns per hour during the week (7) and the hours worked during the week (x); plus the product of the amount he earns per hour during the weekend (9) and the hours worked during the weekend (y):

    7x + 9y

    a) substitute x=8 and y=12

    7 (8) + 9 (12)

    b) substitute y = 5

    7 x + 9 (5) =

    7x + 45 =

    c)

    Substitute y=5 and the expression must be equal to the amount he needs to buy sports equipment (115):

    7x+9 (5) = 115

    Solving for x:

    7x + 45 = 115

    7x = 115-45

    7x = 70

    x = 70/7

    x = 10 hours
