Quizplus · Accepted Answer

Mike sells 3 times as many cars as Bill, so if we let the number of cars Bill sold be x, then Mike sold 3x cars. Together, they sold x + 3x = 4x cars. Given that they sold 640 cars in total, we have 4x = 640. Solving for x gives x = 160 (the number of cars Bill sold), and thus Mike sold 3 * 160 = 480 cars.
