At a sale Jean received a discount of $10.00 on a coat marked $80.00. What was the rate of the discount?

10 / 80 = ?

Convert that answer to a percent.

12.5% or 12 and a half%

To find the rate of the discount, we need to divide the amount of the discount by the original price of the coat and multiply the result by 100 to express it as a percentage.

So, in this case, Jean received a discount of $10.00 on a coat marked $80.00.

The formula to find the rate of discount is:

Discount Rate = (Discount Amount / Original Price) * 100

Substituting the values we have:

Discount Rate = ($10.00 / $80.00) * 100

Calculating this expression will give us the rate of the discount.
