Below are sample questions representative of the exercises included on this worksheet and related 7.54 Cost Benefit and Marginal Analysis skill assessments:

Problem 1Difficulty: Hard

A school can either outsource printing or buy its own printer. Option In-House: buy a printer for $480 today, pay $12 per month for maintenance, and pay $0.03 per page for ink/paper. Option Outsource: pay $0.12 per page with no other costs. The school expects to print 9,000 pages per year for 3 years. Treat monthly maintenance as $144 per year.

Which option has the lower total cost over 3 years?

ABuy the printer (total cost about $1,722) rather than outsourcing (about $3,240).

BOutsource, because per-page pricing is simpler.

CThey have the same total cost.

DOutsource, because there is no upfront cost.

Solution & Explanation:In-house yearly running cost is $144 maintenance + 9,000 × $0.03 = $270, for $414 per year. Over 3 years that is $1,242, plus the $480 printer cost = $1,722. Outsourcing costs 9,000 × $0.12 = $1,080 per year, or $3,240 over 3 years. In-house is lower.

Problem 2Difficulty: Mastery

You’re doing a weekend delivery gig. Your marginal revenue is $22 for each additional delivery. Each delivery also has a $12 fuel/vehicle cost. Your time is valued at $11 per hour, and each delivery takes longer as you get tired: 0.5 hr, 0.6 hr, 0.7 hr, 0.9 hr, 1.1 hr for deliveries 1–5.

Using marginal analysis, how many deliveries should you complete?

A0 deliveries.

B3 deliveries.

C5 deliveries.

D4 deliveries.

Solution & Explanation:Marginal cost per delivery = $12 vehicle cost + ($11×time). MCs: 1) 12+5.5=17.5, 2) 12+6.6=18.6, 3) 12+7.7=19.7, 4) 12+9.9=21.9, 5) 12+12.1=24.1. Do deliveries while MR $22 ≥ MC; stop before the 5th, so 4 deliveries.

Problem 3Difficulty: Mastery

A practice platform requires a one-time setup of 1 hour (no money cost) before you can use it. After setup, each additional hour of practice gives marginal benefits (in dollars of expected grade value) of: $28, $20, $14, $10 for hours 1–4 of practice. You value your time at $15 per hour for all hours (including setup).

How many hours of practice should you do after setup to maximize total net benefit?

A4 hours of practice after setup.

B3 hours of practice after setup.

C2 hours of practice after setup.

D0 hours of practice after setup.

Solution & Explanation:Practice hours have MBs 28,20,14,10 and MC $15 each. Do hours where MB ≥ MC: first two (28 and 20) qualify; third (14) does not. Setup is a fixed cost that you only pay if you practice at all; with 2 practice hours, total net = (28+20) − 15×2 − 15×1 = 48 − 45 = $3 positive, so 2 is best among options.
