| Answer: | 
| 
Variable cost per unit = (Highest Cost (-) lowest Cost) / ( Highest Hours (-) lowest Hours) = ( $ 5,260 (-) $ 2,860 ) / ( 720 (-) 320) = $ 2,400 / 400 = $ 6 Per unit  | 
| Variable cost per unit = $ 6 Per unit | 
| 
Fixed cost   
=   Highest Cost (-) ( Highest Hours x Variable cost per
unit   ) = $ 5,260 (-) ( 720 x $ 6) = $ 5,260 (-) $ 4,320 = $ 940  | 
| Fixed cost = $ 940 |
