Question


A pair of shoes costs $52.99 and the state sales tax is 8%. Use the formula C = p + rp to find the total cost of the shoes, where C is the total cost, p is the price, and r is the sales tax rate.

A.$57.23

B.$60.99

C.$95.38

D.$78.19

1 Answer

  • The pair of shoes costs $52.99, so p = 52.99.
    The state sales tax is 8%, which can be changed to decimal form by dividing by 100: 8/100 = 0.08. So r = 0.08.
    Now you can plug both of these values into the formula to find the total cost of the shoes (c):

    c = p + r*p
    c = 52.99 + (0.08)*(52.99)
    c = 52.99 + 4.2392
    c = 57.2292
    So the total cost of the shoes is $57.23.
