b. (purchase price) x (percent sales tax); then subtracted from the original amount

c. (purchase price) x (percent sales tax); then divided by the original amount

d. (purchase price) x (percent sales tax); then multiplied by the original amount

Answer 1

a is correct

(purchase price) x (percent sales tax); then added to the original amount

Explanation:

When we buy some product. We have to pay tax on their purchasing amount. Tax always calculate as percentage.

First we find percentage of sales tax on purchase price which called sale tax value

Now we add sale tax amount into purchase value to get final payment of product.

Let original or purchase price of any product be p and sale tax on that product is s%

Sale tax value = s% of p = ps/100

Final price to pay = p + ps/100

Hence, (purchase price) x (percent sales tax); then added to the original amount

Answer 2

A. (purchase price) x (percent sales tax); then added to the original amount

Explanation:

We are given,

The purchase amount has sales tax applied to it in order to get the total price.

As, there is a sales tax on the purchase price.

Then, the amount of tax applied = (purchase price) × (percent sales tax)

In order to find the total price, we will add the amount of tax to the original amount.

Thus,

Total Price = (purchase price) x (percent sales tax) + original amount
