Question 178679
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.
