The neighborhood candy store sold 336 candy items this week. Twice as many M&Ms were sold as Snickers, and three times as many Crunch bars were sold as Snicker bars. How many of each kind of candy were sold this week? Show your work.

Respuesta :

amount m&m= x
amount snickers = Y
amount crunch =  Z

x + y + z = 336
x = 2 y
z = 3 y 

2 y + y + 3 y = 336
y = 56
x = 2 . 56 = 112
z = 3 . 56 = 168
