The price of an apple is 1.25$. If you get 20% discount, how much do you have to pay?

To get this answer, use this formula:

Original price times discount in percent divided by 100.

So you would have 1.25 x 20 / 100. Then by solving the multiplication you have 25 / 100. Then divide.

You get the amount saved, which is .25.

That means that you only have to pay $1.00.

Original price times discount in percent divided by 100.

So you would have 1.25 x 20 / 100. Then by solving the multiplication you have 25 / 100. Then divide.

You get the amount saved, which is .25.

That means that you only have to pay $1.00.

You can simply multiply $1.25 by .80 (because 100% or 1.00 -20% or 20=80% or .80) then you will get $1.
