An item is priced at $13.22. If the sales tax is 4%, what does the item cost including sales tax

sales tax = 13.22 *.04

sales tax =.53 (round to the nearest cent)

total cost = cost of item + sales tax

total cost = 13.22 +.53

total cost = 13.75

To determine how much sales tax will be, we need to begin with our price:

$13.22

$13.22 is 100% of the price, before tax. Tax is based on this percentage, so we need to find out what one percent of $13.22 is.

13.22 / 100 =.1322

.1322 is one percent of $13.22. Since we are looking for four percent of 13.22, we multiply our 1% (.1322) by 4.

.1322 x 4 =.5288

$0.5288 is 4% of $13.22. So, we add that to $13.22 to find our answer, after tax.

$0.5288 + $13.22 = $13.7488, or $13.75 if you round up.
