Answer:

Company B

Step-by-step explanation:

Given

See attachment for graph

Required

Company with the least additional fee

This means the y-intercept and it represents the flat fee

To get the y-intercept, we simply write out the point where [tex]x= 0[/tex]

From the graph of A, we have:

[tex](x,y) = (0,70)[/tex]

Additional Charges = 70

From the table of B, we have:

[tex](x,y) = (0,50)[/tex]

Additional Charges = 50

From the equation of C, we have:

[tex]y=10x+ 90[/tex]

[tex]y(0) = 10 * 0 + 90[/tex]

[tex]y(0) =0 + 90[/tex]

[tex]y(0) =90[/tex]

Additional Charges = 90

By comparison. company B has the least additional fee because: [tex]50 < 70 < 90[/tex]
