Question 178679: Foam fingers sold for $5. Spirit bracelets for $4. You sold 40 more foam fingers than bracelets and earned $965. Write a system of equations to describe this situation.

Answer by HyperBrain(694)   (Show Source):
You can put this solution on YOUR website! Let x=no. of foam fingers sold
y=no. of spirit bracelets sold
then
5x=amount earned on foam fingers
4y=amount sold on spirit bracelets
You sold 40 more foam fingers than bracelets;: so,
x=y+40
you earned $965. so,
5x+4y=965
substituting x=y+40,
5(y+40)+4y=965
5y+200+4y=965
9y+200=965
9y=765
y=85
x=y+40=85+40=125
Therefore, you sold 125 foam fingers and 85 spirit bracelets.
