Question

Preston Concrete is a major supplier of concrete to residential and commercial builders in the Pacific Northwest. The company's general pricing policy is to set prices at $115 per cubic yard. Deliveries for 2018 were 410,000 cubic yards. Total costs were:

Material costs	$26,199,000
Yard operation costs	$6,150,000
Administrative costs	$1,517,000

$4,858,500 of the estimated total yard operation costs were variable, and all of the administrative costs were fixed. In addition to the costs above, estimated fixed delivery costs were $215,000 for the year, and estimated variable delivery costs were $8.00 per mile and $42.50 per truck hour. The rate per mile reflects the fact that more miles result in more gas, oil, and maintenance. The rate per truck hour reflects the fact that trucks that are waiting at a jobsite are kept running (so the concrete mix won't solidify), and drivers continue to get paid during that time.

Near the end of 2018, Fairview Construction Company asked for a delivery of 5,300 cubic yards of concrete but was unwilling to pay the regular price; it was only willing to pay $88 per cubic yard. Preston estimated that the job would require 6,800 miles of driving and 250 truck hours. The housing market in the Pacific Northwest had slowed during recent months, leaving Preston with enough capacity to fill the order, but its sales manager was reluctant to commit to such a reduced price.

If Preston accepted the offer, what would the profit or loss be (enter a loss as a negative number)?

My work:

Incremental Value: 5,300 (88) = 466,400

Incremental Costs

Material cost: 63.9 (5,300) = 338,670

Yard Operation Cost: 11.85 (5,300) = 62,805

Delivery cost: 6,800 (8) + 42.50 (250) = 65,025

Net loss: 466,400 - 338,670 - 62,805 - 65,025 = -100

so there is a loss of $100. Where did I go right/wrong? I have only one attempt remaining.

Answer 1

Incremental analysis

Incremental revenue (5300*88)	466400
Incremental Cost
Material Cost (5300*63.9)	338670
Yard operation cost (5300*11.85)	62805
Delivery cost (6800*8+42.50*250)	65025
Total incremental Cost	466500
Incremental profit (loss)	-100

So company should not accept the offer
