How do i find selling price or sale price

The rate is usually given as a percent.To find the discount, multiply the rate by the original price.To find the sale price, subtract the discount from original price.

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
