Anna works in a clothing store and receives a 20% employee discount. If Anna decides to buy a $120 coat, what will her total cost be with 5.5% tax.

solution: In order to solve this problem you must first calculate Anna's 20% discount. Hint: Change the 20% into a decimal. Next, subtract the discount fromthe origional price, this gives you Anna's sale price. Calculate the sales tax, again by changing the percent into a decimal. Finally, add the sale price and sales tax together.


$120 x .2 = $24 (discount)
$120 - $24 = $96
$96 x .055 = $5.28
$96.00 + $5.28 = $101.28 (Anna's final cost)
