The answer to your question is: Burger = $4.45, Pizza = $2.2

Step-by-step explanation:

Jason = $15.5 for 3 slices of pizza + 2 burgers

Susan = $20 for 1 slice of pizza + 4 burgers

Pizza = p

burger = b

System of equations

Jason 3p + 2b = 15.5 (I)

Susan p + 4b = 20 (II)

Solve system by elimination

Multiply (II) by - 3

3p + 2b = 15.5

-3p - 12b = - 60

-10b = - 44.5

b = - 44.5/-10

b = $4.45

p + 4 (4.45) = 20

p + 17.8 = 20

p = 20 - 17.8

p = 2.2

One slice of pizza costs $2.2 and one burger cost $4.45
