Question

How much profit will the business make on the sale of a couch that is marked up by 1/3 and then sold at a 1/5 off discount if the original price is 2,400

Answer 1

1/5 (2400 + 2400*1/3) = x
1/5 (2400 + 800) = x
1/5 (3200) = x
640 = x

Answer 2

1/5 (2400 + 2400*1/3) = r
1/5 (3200) = r
640 = r
