Question 933646
At an awards banquet, the bill for three glasses of milk and five seafood dinners is $38.50, whereas the bill for one glass of milk and two seafood dinners is $15.15.
 1. Write a system of two equations to model this problem. Let m stand for the price of a glass of milk and let s stand for the price of a seafood dinner.
Value Eq:: 3m + 5s = 38.50
Value Eq::  m + 2s = 15.15
-------
 2. Use substitution to solve the system of equations.
Substitute for "m" and solve for "s"::
3(15.15-2s) + 5s = 38.50
45.45 - 6s + 5s = 38.50
-s = -6.95
seafood dinner cost $6.95
----
Solve for "m" using m = 15.15-2(6.95) = $1.25
-------------------------------
 3. What would be the bill for one glass of milk and one seafood dinner?
