Solving the system of equations, it is found that the before-tax price of a chicken dinner is of $15.5.
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are:
The system is given by:
27c+ 17s = 809.50
46c + 34s = 1,495.00
Multiplying the second equation by -0.5 and adding with the first we can remove s, hence:
27c+ 17s = 809.50
-23c - 17s = -747.50.
4c = 62.
c = 62/4.
c = 15.5.
The before-tax price of a chicken dinner is of $15.5.
