Fixed costs remain constant at $450,000 per month. During high-output months variable costs are $300,000, and during low-output months variable costs are $125,000. What are the respective high and low indirect-cost rates if budgeted professional labor-hours are 24,000 for high-output months and 5,000 for low-output months?

High indirect-cost rate is $31.25

Low indirect-cost rate is  $115

Explanation:

It is noteworthy that the indirect cost-rate refers to the sum of variable cost per hour+fixed cost per hour

High indirect-cost rate=variable cost per hour+fixed cost per hour

High output:

variable cost per hour=total variable costs/number of hours

fixed cost per hour=Fixed costs/number of hours

variable cost per hour=($300,000/24,000)=$12.5

fixed cost per hour =($450,000/24000)=$18.75

high indirect cost-rate=$12.5+$18.75=$31.25

Low output:

variable cost per hour=total variable costs/number of hours

fixed cost per hour=Fixed costs/number of hours

variable cost per hour=($125,000/5,000)=$25.00

fixed cost per hour =($450,000/5,000)=$90

low indirect cost-rate=$25+$90=$115

the correct answer is d. wealthy colonists to take care of the less fortunate. hope this
