Step-by-step explanation:

lets use variables

dolls = d

remote cars = r

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 2. Answer: C.$146.43
