Original price percent of discount sale price $ 25% $40

X= original price

Original $ - % off original $= total paid

x - 25%x= $40
x - 0.25x= 40
Combine like terms
0.75x= 40
Divide both sides by 0.75
x= $53.33 original price

Hope this helps! :)

You can use a calculater and divide the minutes by the $$, hope that you
