Question

Charlie bought a $60 radio on sale off 5% off. How much did he pay including 5% sales tax?

Answer 1

See solution

Explanation:

`color(blue)("Assumption: The price of $60 excludes tax")`

If 5% discount is removed then the remainder is:

`(100-5)/100 = 95/100->95%`

So the sale price is: `95/100xx$60 =$57`

The associated tax for this price is: `5/100xx$57 = $2.85`

The total sale price including the tax is `$57+$2.85= $59.85`
