Question

5. SHORT ANSWER A pair of jeans that normally sells for $35 is on sale for 20% off Find the sale price of the jeans. Then find the total cost of the jeans if the sales tax rate is 6%.

Answer 1

First, find the amount the sale is worth. To do such a thing, calculate 20% of 35$ like this
(35 * 20) / 100 = ?

To find the cost of 1 jean, take the sale's worth off the full price.
35 - ? = $

Then, multiply it by 6, for 6 jeans.
$ * 6 =

Answer 2

What you do is:
35 x 0.8 = $28
(You use 0.8 because you are paying 80% of the original price)
Then you do:
28 x 1.06 = $29.68
(You use 1.06 because it is 6% tax per dollar)
