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.

Answer 1

using the rule of 3 simple you can calcule the 60% of $30,65
30,65 mean 100%
x mean 60% cross multiplie and calcule the value of x

x = 30,65*60/100 = ?

so what get subtract from 30,65 and check than you get this 18,39 or not
