    Answer:

    C . $146.43

    Step-by-step explanation:

    lets use variables

    dolls = d

    remote cars = r

    create an equation for the cost of dolls :

    3 * 19.99 = $59.97

    Create an equation for the cost of the remote cars

    4 * 21.99 = $ 87.96

    since there was a discount for each car bought, deduct from total cost

    $87.96 – 4*3 = $75.96

    now add the cost of the dolls and cars as well as the shipping cost :

    59.97 + 75.96 + 10.5

    = $ 146.43
