at a fair, $540 was made selling candy bars, funnel cakes & sodas. all three items were sold for $20.00 three times as many candy bars were sold as funnel cakes. five times as many sodas were sold as funnel cakes. find the number of sodas sold.

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?
At a fair, $540 was made selling candy bars, funnel cakes, and sodas. All three items were sold for $2.00 each. three times as many candy bars were sold as funnel cakes. five times as many sodas were sold as funnel cakes. find the number of sodas sold.
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.
