Answer:
fixed cost = $7520
so correct option is D. $7,520
Step-by-step explanation:
given data
January production = 29,000 hours
maintenance costs = $11,000
July production = 10,000 hours
maintenance costs = $8,800
to find out
what are the fixed costs
solution
we get here first variable cost that is express as
Variable cost per hour =

Variable cost per hour =

Variable cost per hour = $0.12
so fixed cost will be
fixed cost = maintenance costs - January production × Variable cost per hour
fixed cost = $11000 - ( $29000 × $0.12 )
fixed cost = $7520
so correct option is D. $7,520
