In a linear programming formulation of single-period capital rationing, the shadow price of the capital constraint is $0.35. What does this indicate?

A shadow price of $0.35 means each additional dollar of capital would raise total NPV by about $0.35, within the range over which the solution remains valid. It shows the maximum premium worth paying to relax the constraint, not a cost of capital or IRR.

  1. AEach extra $1 of capital available would increase total NPV by $0.35, within the relevant rangeCorrect
  2. BThe firm's cost of capital is 35%
  3. CEach project returns 35% IRR
  4. DTotal NPV falls by $0.35 for each extra $1 of capital

Explanation

The shadow price is the marginal increase in the objective (NPV) from relaxing a binding constraint by one unit, valid within a range. It is useful for judging whether raising extra funds is worthwhile.
