Answer:
The cost of a candy bar is [tex]\$1.5[/tex]
Step-by-step explanation:
Let
x----> the cost of a soda
y----> the cost of a candy bar
we know that
[tex]3x+4y=10.17[/tex]-----> equation A
[tex]2x+5y=10.28[/tex]-----> equation B
Solve the system of equations by graphing
Remember that the solution of the system of equations is the intersection point both graphs
The solution is the point [tex](1.39,1.5)[/tex]
see the attached figure
therefore
The cost of a soda is [tex]\$1.39[/tex]
The cost of a candy bar is [tex]\$1.5[/tex]
