An electronics store offered a videodisc player for $225. This price was the sale price, after the regular price had been discounted 40%. What was the regular price?
Let's put the regular price = x.
x*(1-40%)=225
x=225/40%=225/(1-40%)=225/(1-0.4)=225/0.6=375
x=375
Therefore, the regular price of the videodisc player is $375
Hope this helps.
