a. 46.01
b. 18.03
c. 16.35
d. 45.45

Answer 1

c. 16.35

Explanation:

First we need to determine how much we spent before tax

We bought 3 CDs at 13.99

3*13.99 = 41.97

Now we need to determine the tax

tax = price * tax rate

tax = 41.97 * .04

tax =1.68

The total cost is price + tax

total cost is 41.97+1.68

total cost = 43.65

We have 60.00

The change is 60.00-43.65

16.35

Answer 2

Find the total of the 3 CD's by multiplying 13.99 by 3:

13.99 x 3 = 41.97

Now add the tax:

41.97 x 1.04 = 43.65 ( total of 3 CD's with tax.)

Subtract the total of the CD's from the amount you have to find the change:

60 - 43.65 = 16.35

The answer is c. 16.35
