Question

A greeting card cost four dollars before tax. A customer has a 15% discount. Then the 5% sales tax is added. How much will the customer pay for the card?

Answer 1

Given:

Greeting card cost before tax = $4

Discount = 15%

Sales tax = 5%

To find:

How much will the customer pay for the card?

Solution:

It is given that the cost of the greeting card before tax is $4.

After 15% discount, the cost of the greeting card is:

Cost of card after discount $=4-\dfrac{15}{100}\times {4}$

                                             $=4-0.6$

                                             $=3.4$

The cost of card after 5% sales tax is:

Cost of card after tax $=3.4+\dfrac{5}{100}\times 3.4$

                                    $=3.4+0.17$

                                    $=3.57$

Therefore, the customer will pay $3.57 for the greeting card.
