Question

An item regularly priced at $80 is on sale for 20% off. There is a 3% sales tax. What will be the total cost of the item on sale?

Answer 1

Answer:

The total cost of the item on sale is:

                   $\ \ 65.92$  

Step-by-step explanation:

The regular price of the item is:  $ 80

Also, it is given that the item is on a sale of 20%.

Hence, the item is to be paid at a rate of (100-20)%=80% of the regular price of the item.

Hence, after the offer the item will cost:

      $=80\%\ of\ 80\\\\i.e.\\\\=\dfrac{80}{100}\times 80\\\\i.e.\\\\=\ \ 64$

The sales tax on the item is 3%.

This means that the tax on the item is:

$=3\%\ of\ 64\\\\=\dfrac{3}{100}\times 64\\\\=\ 1.92$

Hence, the total cost of the item on sale is:

      $=\ 64+\ 1.92\\\\=\ \ 65.92$

Answer 2

80 - 20% = 64

Now we have to add the tax, so: 64 + 3% = $65.92

The answer should be $65.92.

I hope this helped,
