The key club is working a concession stand at the school fair. They are selling cotton candy for $3.50 and soda for $1.50. At the end of the first shift they made $120. The club sold a total of 60 items. How much cotton candy and soda did they sell?
Equation:
Let c=cotton candy
s=soda
---Equations---
s+c=60
3.5c+1.5s=120
3.5c+3.5s=210
3.5c+1.5s=120
2s=90
s=45
So, they sold 45 sodas and 15 cotton candies.
YUMMMMM!!!!
