Answer:
<em>The total price of the CD is $14.18</em>
Step-by-step explanation:
<u>Percentages </u>
We can compute additive or subtractive percentages by using these formulas. If we have a number X and want to increase it by Y%, then the increase is xY/100. Thus the new value for the number is x+xY/100 or equivalently
If we want to decrease by Z%, the new value is
The regular price for a CD is X=$15. The CD is Z=10% off, so the sale price is
But we have to add the tax of Y=5%, so the final value is
The total price of the CD is $14.18
