Answer:
The total cost will be "$1,279,286.25".
Explanation:
The total cost at 125000 Km will be:
[tex]=125000\times 12.520[/tex]
[tex]=1,565,000[/tex] ($)
The total cost at 90000 Km will be:
[tex]=90000\times 16.5[/tex]
[tex]=1,485,000[/tex] ($)
The variable cost will be:
[tex]=\frac{(1,565,000 - 1,485,000)}{(125000 -90000) }[/tex]
[tex]=2.28571[/tex] ($)
Now,
Fixed cost = [tex]Total \ cost -variable \ c ost[/tex]
= [tex]1,565,000 - 125000\times 2.28571[/tex]
= [tex]1,279,286.25[/tex] ($)
