Question

If the regular price of an item is X dollars, what is the discount price in dollars?

Answer 1

Answer:

First, we have to know the discount percentage.

Let's say that is 20% off, this would be in decimal number 0.20.

Now, if the regular price is $\ X$, then the dollars discounted are

$(0.20)(\ X)$

And the final price is

$\ X-\ 0.20X=\ 0.80X$

Which means that the final price is 80% of the regular prices.

Now, for a general case, let's call $Y\%$ the percentage discount, in this case, the final price would be

$\ X-\ (0.Y)X=\ (1-0.Y)X$

Answer 2

Answer:

Step-by-step explanation:

x/regular price=y

1-y=discountx100

So, say you get a pair of shoes that are normally $100 and you pay 75. 75/100=.75. 1-.75=.25x100=25. This means you got a 25% discount.
