Final answer:
The total cost of a compact disc that costs $14.99 plus a 5% state sales tax is $15.74.
Step-by-step explanation:
First, find the amount of sales tax. In doing so, first convert the percent to a decimal and then multiply by the total cost.
For a compact disc that costs $14.99 and has a 5% state sales tax:
$14.99 x 0.05 = $0.75
The total cost of the compact disc, including sales tax, is $14.99 + $0.75 = $15.74.
