If shoes cost 48$ but have a 25% discount how much are they

-1 dolares

not sure if there is tax or not, but there are two ways you could do this. 

#1

$48 x 0.25 = how much discount.

$48 - how much discount = total 

#2

$48 x 0.75 (100%-25%) = total. 

Either way, you should get the same answer...
