A shirt was originally priced at $60. The store is having a 20% off sale. How much will you pay for the shirt after the discount (not including tax)? Round your answer to the nearest cent

We have to calculate the final price of the shirt.
We have to apply the 20% discount to the list price, that is $60.
We can do it as:
[tex]\begin{gathered} P=60-0.2\cdot60 \\ P=(1-0.2)\cdot60 \\ P=0.8\cdot60 \\ P=48 \end{gathered}[/tex]Answer: the shirt will cost $48 before tax.
