    Answer:

    The cost of soft drink is $0.95

    Step-by-step explanation:

    Let the cost of hot dog be x

    Cost of 2 hot dogs = 2x

    Let the cost of soft drink be y

    Cost of 3 soft drinks = 3y

    At a cost restaurant the cost for a hot dog and a soft drink is $2.10.

    So, x+y=2.10

    The cost for two hot dogs and three soft drinks is $5.15

    So, 2x+3y=5.15

    Plot the lines on the graph:

    x+y=2.10 –Purple line

    2x+3y=5.15 — Black Line

    Intersection point =(x,y)=(1.15,0.95)

    Hence The cost of soft drink is $0.95
