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]
