Use this for “An activity takes 10 days for $12,000, or 6 days at most for $15,200. What does cutting it by 3 days cost?”

Use this for “The critical path is expected to take 42 days, and its activity variances add to 9 days². What is the chance the job is done in 46 days?”

Use this for “705 m³ of bank earth swells 25% when dug and shrinks 10% when compacted. What are the loose and compacted volumes, and how many 12 m³ truck loads is it?”

Use this for “3200 m³ of earth is hauled an average of 450 m, with 150 m of free haul and overhaul paid at $0.85 per m³·sta. What does the overhaul cost?”

Use this for “A building cost $2,400,000 when the cost index stood at 11,200. The index is 13,350 now, and the city index is 92.5. What would it cost to build there today?”

Use this for “A crew took 120 hours to build the first of many identical forms. On an 85% learning curve, how long does the 10th one take?”

Use this for “A $420,000 loader sells for $60,000 after 10,000 h; it costs $48/h to run and its operator earns $45/h. At 150 m³/h, what does each cubic meter cost?”

Use this for “Trucks of 14 m³ take 18.98 min for each cycle, and the loader fills one in 4.2 min. With 4 trucks at 50 min/h, how many trucks balance the loader, and which one limits production?”
