Answer:
Variable operating cost per mile = $0.2
Fixed operating cost = $215
Income  at 3,700 miles = $895
Explanation:
The variable cost per mile =
(cost at high activity - cost at low activity)/(high activity - low activity)
Fixed operating cost = cost at high activity - (VC/mile × high activity)
So we can apply the formulae as follows:
The variable cost per mile = (1,095 - 875)/(4,400-3,300)= $0.2 per mile
Fixed cost = $1,095 - (0.2×4,400)=$215
Variable operating cost per mile = $0.2
Fixed operating cost = $215

Sales value = (3,700 miles × $0.50 per mile)    1,850
Variable cost   (3,700×  $0.2)                (740)
Contribution                               1,110
Less Fixed cost                            (215)
Income                                   895
