Question

Chase is trying to calculate the total cost of the T-shirt that he's buying. Since it's on sale, he first found the amount of the discount and added that to the original price. Next, he subtracted off the amount of the sales tax. His total, though, is different than the sales clerk's total. What did Chase do wrong?
#He should have subtracted the discount.
#He should have added the sales tax.
#He should have subtracted the discount and added the sales tax.
#Nothing. The sales clerk has the wrong total.

Help please?

Answer 1

Answer:

He should have subtracted the discount and added the sales tax.

Step-by-step explanation:

Given information is -

The T-shirt is on sale.

Chase first found the amount of the discount and added that to the original price. (This is wrong as discounts are always subtracted from the original price)  

Next, he subtracted off the amount of the sales tax. (Sales tax has to be always added to the final amount)

Lets take an example.

Suppose you bought a t shirt that had an original price of $50. It was on $20 discount and the sales tax was 5%. So, total bill will be :

New price = $50-20=30$ dollars

Sales tax amount = $0.05\times30=1.50$ dollars  

Total bill = $30+1.50=31.50$ dollars

This is the correct way to calculate.

So, the correct option is -

He should have subtracted the discount and added the sales tax.
