Answer:
A.
Step-by-step explanation:
Total costs are equal to total fixed costs plus total variable costs.
TC = FC + VC
Per unit, the equation is:
Total costs per unit = (total fixed costs / units of production) + unit variable costs.
In this example, the equation is:
TC $36.000 = FC + VC $27.000
$36.000 - $27.000 = FC
$9.000 = FC
FC per unit = FC / units of production
FC per unit = $9.000 / 9.000 units of production
FC per unit = $1
