Sara is serving wings and burgers at her party. Wings cost $6.00 per serving and burgers are $3.00 each. Sara knows that at leas
t 4 of her friends want wings. Sara must spend less than $45.00. Sara graphs a system of inequalities to determine how many servings of each kind of food she could serve to stay within her budget.
According to the dark blue area on the graph, which coordinate pair satisfies the system for the number of wing servings and burgers that Sara can serve?
A) (5, 4)
B) (2, 5)
C) (8, 3)
D) (6, 5)

Step-by-step explanation:
<u>Cramer's Rule</u>
It's a predetermined sequence of steps to solve a system of equations. It's a preferred technique to be implemented in automatic digital solutions because it's easy to structure and generalize.
It uses the concept of determinants, as explained below. Suppose we have a 2x2 system of equations like:
We call the determinant of the system
We also define:
And
The solution for x and y is
(a) The system to solve is
Calculating:
The solution is x=2, y=-1
(b) The system to solve is
Calculating:
The solution is x=2, y=2
(c) The system to solve is
Calculating:
The solution is
(d) The system to solve is
Calculating:
The solution is x=-2, y=-7
