ss7ja [257]

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.
