Question 900882
I have two equations for this problem, I am just not sure how to solve it. The problem is; At a benefit concert, 900 tickets were sold and $2700 was raised. If there were $2 and $5 ticket, how many of each were sold? 
I have x+y= 900 and then $2x+$5y=$2700

Getting from the "word problem" to 2 eqns is what most can't seem to do.  Good work on that.
---
x+y= 900
2x+5y=2700 (the $ are not needed)
Multiply the 1st eqn by 2
2x + 2y = 1800
2x + 5y = 2700
-------------------------- Subtract
-3y = -900
y = 300
==========
x+y = 900
x = 600
