  • Jasper has $x in wallet. His father gave him another $40.
    a)
    Total amount money Jasper had:
    $x + $40 = $(x + 40)

    Jasper gave half of the total amount of money to charity:
    *Half = divided by 2
    $(x + 40) ÷ 2 = $([tex] \frac{1}{2} [/tex] x + 20)

    b)
    If x = $40
    Jasper's money
    $([tex] \frac{1}{2} \times 40[/tex] + 20)
    =$(20 + 20)
    =$40
