Answer:
Candy bar: $1/each
Pop: $2/each
Step-by-step explanation:
4x+3y=10
3x+5y=13
Where x = number of candy bars and y = number of pops.
Create an augmented matrix like so
Using Gaussian Elimination reduce the matrix to reduced row echelon form.
As you can see x = 1, and y = 2.
Thus each candy bar is $1 and each pop is $2.
