Explanation:

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

If 5% discount is removed then the remainder is:

$\frac{100 - 5}{100} = \frac{95}{100} \to 95 %$ $(100-5)/100 = 95/100->95%$

So the sale price is: $\frac{95}{100} \times $ 60 = $ 57$ $95/100xx$60 =$57$

The associated tax for this price is: $\frac{5}{100} \times $ 57 = $ 2.85$ $5/100xx$57 = $2.85$

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