Toni goes to a department store and buys two shirts marked the same price. She
pays full price for the first shirt but gets a 40% discount on
the second shirt. If she pays a total of $32.40 for the two
shirts, how much did she pay for the second shirt?
Let X be the price of the second shirt.
So, 60/100*X+X=32.40
So, 1.60X=32.40
So, X=32.40/1.60
So, X=$20.25. Answer: \boxed{20.25}.
