Math Percentage question

Question

A jacket usually sells for $56.00. If the jacket is 20% off, and sales tax is 8%, what is the total price of the jacket, including tax?

Answer 1

This can be done by using the "percentage of a number" formula. Take the percentage and pretend it is a whole number with a decimal at the end of it, and then move the decimal two spots to the left.

Example: 40% = 40.0 = 0.40 If the percent is a single digit number-- 2% = 2.0 = 0.02

After you know what decimals you are working with, you can multiply the amount of dollars times the decimal number you converted.

Example: $50 with a 40% discount would be $50 x .40 = $20 in savings. Take $50 base cost minus the $20 to see that you would pay $30 for the item.

Next step is to add the tax, instead of subtract it. So take the now $30 for the item, and multiply by 0.02 = $0.60. A 2% tax means you will pay 60 cents in tax, resulting in a full price of $30.60.

How is how it looks in your scenario, with example costs: A jacket usually sells for $50.00. If the jacket is 40% off, and sales tax is 2%, what is the total price of the jacket, including tax?

1. Convert 40% to 0.40
2. $50 x 0.40 = $20 saving
3. $50 - $20 = 30 base pay for the item
4. Convert 2% to 0.02
5. $30 x 0.02 = $0.60 paid in tax
6. $30 + $0.60 = $30.60 total paid
