Question

A video game that usually costs $30.65 is marked down 60%. Kelvin determined that the new price of the game would be $18.39. Look at Kelvin’s work and find his error.

($30.65)(0.60) = $18.39

Answer 1

notice how he multiplied the inital price by 0.60 to obtain the final price. however, a 60% markdown means that the new price is 40% of the original price, not 60%.
