Answer:

Each slice of pizza cost $2.2

Each burger cost $4.45

Step-by-step explanation:

Let

x -----> the cost of one slice of pizza

y ----> the cost of one burger

we know that

Jason

[tex]3x+2y=15.50[/tex] -----> equation A

Susan

[tex]x+4y=20[/tex] -----> equation B

Solve the system of equations by graphing

Remember that

The intersection point both graphs is the solution sof the system of equations

The solution is the point (2.2,4.45)

see the attached figure

therefore

Each slice of pizza cost $2.2

Each burger cost $4.45
