A lamp was marked up 100% from an original purchase cost of $30. Yesterday, Suzie sold the lamp, earning a 20% commission on the sale price. How much commission did she make from this sale?


Respuesta :

100% markup means the price is double what it was bought for, $30. 30x2=60 dollar sale price. A 20% commision would be $12. 60 x 0.2=12
