If they sell exactly 500 fruit bars, how many boxes of popcorn will they need to sell to make a total of $300? 30 cents fruit bars. 60 cents box of popcorn

Respuesta :

Amount to raise: 300
popcorn = 60 cts
fruitbars = 30 cts
.
they sold 500 fruit bars = 500 x 0.30 = 150

(300 - 150)/0.6 = 150/0.6 = 250 this is how many popcorn they need to sell
