Question

A game that costs $72 is on sale for 20% off. It has a sales tax rate of 7.5% 20 on the sale price. What is the final cost of the game? ​

Answer 1

$61.92

Explanation:

Lets start by applying the sale(discount) on the game. 20% off is synonymous with having 80% of something(the remaining part), so we can multiply 72*.8 in order to get $57.6

Now lets apply sales tax. A simple way to calculate total price when a tax or increase is present is by adding 100% to the % and multiplying. In this case, we would have
`1.075 * 57.6 = $61.92`
