Question

what is the formula of Discount​

Answer 1

Step-by-step explanation:

Step 1:

Remember the formula for finding the discount price of an item. Where S = sale price, r = discount percentage rate and p = original price, the discount formula is:

S = p - rp

Step 2:

Convert the percentage rate into a decimal - remove the percent sign and move the decimal two places to the left. If there's no decimal, assume one just to the right of the ones place. Here, as you can see, 20% = 0.20.

Step 3:

Insert values (including decimal value of rate) into the discount formula:

S = 125 - 0.2(125)

Remember that when two variables are next to each other, it means that you multiply them.

Step 4:

Solve the equation for S:

S = 125 - 25 = 100

Step 5:

Format the answer with the currency notation, or in this case, dollars, leaving us with $100.
