The regular selling price of a pair of men's jeans is $39.99. The markdown rate is 20%. What is the sale price of the jeans to the nearest cent?

Take the original price, multiply it by 20% (you have to move the decimal place two to the left, so it becomes. 2), then subtract the answer from the original price.

39.99*.2 = $7.998

39.99-7.998 = $31.99

If you wanted to, you could also round the $7.998 to $8.00. Your answer would be the same.
