You can put this solution on YOUR website! A large group goes to a restaurant and orders chicken dinners for $8 and steak dinners for $9. If 27 people spend $235, how many have chicken and steak?
--------------------
Equations:
People Eq: c + s = 27 people
Value Eq: 8c +9s = 235 dollars
-------------------
8c + 8s = 8*27
8c + 9s = 235
-----
Subtract and solve for "s":
s = 19 (# of people who ordered steak)
----
Solve for "c":
c + s = 27
c + 19 = 27
c = 8 (# of people who ordered chicken)
