The computer you have been saving for is on sale. You have $750 saved to purchase it. The retail price of the computer is $875, but this week it is discounted 15%. There is a 7.25% sales tax added to the price of the computer. What is the final price of the computer, including all discounts and sales tax?

a) $746.38
b) $775.64
c) $789.75
d) $820.93

Answer 1

To find the final price of the computer, calculate the discounted price by subtracting 15% of the retail price from the retail price, and then add the sales tax of 7.25% to the discounted price. None of the provided answer choices exactly match the calculated final price of $797.72, so there may be an error in the question.

Step-by-step explanation:

The question is to calculate the final price of the computer after both the discount and the sales tax are applied. To do this, first find the discounted price:

Retail price x Discount rate = Discount amount
$875 x 0.15 = $131.25

Subtract the discount amount from the retail price:

Retail price - Discount amount = Discounted price
$875 - $131.25 = $743.75

Next, calculate the sales tax on the discounted price:

Discounted price x Sales tax rate = Sales tax amount
$743.75 x 0.0725 = $53.97
Add the sales tax to the discounted price to get the final price of the computer:

Discounted price + Sales tax amount = Final price
$743.75 + $53.97 = $797.72

Since none of the provided answer choices exactly match the calculated final price of $797.72, this implies a possible typo or error in the options provided. The closest answer option to the calculated value is c) $789.75.
