Question

Eli and her sister are buying a present for their father. They want to buy him a tie that sings jingle bells. The Thai which is regularly $35 is on sale for 40% off because it is after the winter holidays. The girls will split the cost evenly and their mother gave them $15 to help with the cost of the tie. If the tax is 8%, how much will Eli and her sister each have to spend on their father's tie?

Answer 1

Explanation:

The regular cost of the tie = $35

There is a sale for 40% off.

`\text{Discount}=40\%\text{ of \$35}=(40)/(100)*35=14`

Thus, the price after the discount will be:

`35-14=\$21`

Next, the tax is 8%.

`\text{Tax}=8\%\text{ of 21=}(8)/(100)*21=\$1.68`

Therefore, the total price at which the tie is purchased will be:

`21+1.68=\$22.68`

Since their mother gave them $15 to help with the cost of the tie, subtract 15.

`22.68-15=\$7.68`

This amount, $7.68 is the split between Eli and her sister.
