Let x = # of candy bars sold

y = # of funnel cakes sold

z = # of sodas sold

All three of the items were sold for $540; although, it's confusing because you then say all three items were sold for $20? "...three times as many"... Perhaps I am misreading this, but can you write the word problem out exactly as it is given to you? - Jan 18th 2007, 04:55 PMblame_canada100made a mistake!

Thank you, this is much clearer.

c = number of candy bars sold

f = number of funnel cakes sold

s = number of sodas sold

c = 3f

s = 5f

c + f + s = 270

3f + f + 5f = 270

9f = 270

f = 30

c = 90

s = 150

Thus, 150 sodas were sold, 90 candy bars were sold and 30 funnel cakes were sold.

Check to see that it works:

2*150 + 2*90 + 2*30 = 300 + 180 + 60 = $540

Yes.

"Find the number of sodas sold."

The number of sodas sold = 150.
