Answer:
The original selling price was [tex]\$75[/tex]
Step-by-step explanation:
Let
x-----> the original selling price
we know that
[tex]100\%-20\%=80\%=80/100=0.80[/tex]
so
[tex]0.80(x)=60[/tex] -----> equation that represent the situation
solve for x
Divide by 0.80 both sides
[tex]x=60/0.80=\$75[/tex]
