Final answer:
After calculating the sales tax of 6.75% for the $69.99 CD player, which is $4.72, and adding it to the original price, the total cost is $74.71. The correct total price is not included in the provided options.
Step-by-step explanation:
To calculate the total price of the CD player after including sales tax, you first have to find the amount of sales tax to be added to the original price. The sales tax rate is given as 6.75%, which you convert into decimal form by dividing by 100, which makes it 0.0675. Then, you multiply the original price of the CD player by this decimal to find the amount of sales tax that will be added:
$69.99 × 0.0675 = $4.724325.
Round this number to the nearest cent which gives you $4.72 in sales tax. To find the total cost of the CD player, add the original price with the calculated sales tax:
$69.99 + $4.72 = $74.71.
Therefore, the total price of the CD player including sales tax is not listed among the options A, B, C, or D provided.
