NPV ≈ $25,000 → Accept the project

NPV ≈ -$10,000 → Reject the project

NPV ≈ $0 → Indifferent between accepting and rejecting

NPV ≈ $70,000 → Accept the project

Crane B is preferred due to its lower equivalent annuity, despite higher per-year costs.

Crane A is financially superior because of its longer replacement cycle.

Crane A is more cost-effective because its NPV is higher.

Because it would result in cost decreasing with scale, violating the time value of money.

Because it would imply decreasing marginal costs as capacity increases.

Because it would imply diseconomies of scale, where doubling capacity more than doubles the cost.

Because power-law models require B<0B<0 to reflect inflation effects.
