Answer:
The prices for a calzone and for soda as an ordered pair (c,s) is (5,1)
Step-by-step explanation:
Let c be the prize of calazone 
Let s be the prize of soda
She buys two calzones and three sodas she pays $13
So, 2c+3s=13
She buys three calzones and two sodas she pays $17
So, 3c+2s=17
Plot the equations on graph
 2c+3s=13 --- Green
3c+2s=17 --- Blue
Intersection point will give the intersection point 
So,(c,s)=(5,1)
So, Option c is correct
