You can put this solution on YOUR website! At the last dance at J.C. Richardson, 130 people in total attended. If a student has to pay $4.50 to come and a visitor has to pay $6.50 to come, how many students showed up if $617.00 was collected in total?
-------------------
People Equation:: s + v = 130
Value Equation:: 4.5s + 6.5v = 617 dollars
---------------------------------
Modify for elimination::
65s + 65v = 65*130
45s + 65v = 6170
------------------
20s = 2280
# of students = 114

You can put this solution on YOUR website! s+v = 130 subtract s from both sides: v = 130-s
Next:
4.50s+6.50v = 617 substitute for v:
4.50s+6.50(130-s) = 617
= 4.50s+845-6.50s = 617
= -2s = -230 divide both sides by -2, and remember -/- = +
s = 115
115 students showed up.
