In problem 6.1 , assume that the 2,000 level is the ‘best estimate’ of annual demand. Also assume that only Machine A is available.

(a) Should the business acquire Machine A on the basis of its NPV?

(b) Carry out a sensitivity analysis on the decision recommended in (a).

Data from problem  6.1

Easton Ltd needs to purchase a machine to manufacture a new product. The choice lies between two machines (A and B). Each machine has an estimated life of three years with no expected scrap value.
Machine A will cost £15,000 and Machine B will cost £20,000, payable immediately in each case. The total variable costs of manufacture of each unit are £1 if made on Machine A, but only £0.50 if made on Machine B. This is because Machine B is more sophisticated and requires less labour to operate it.
The product will sell for £4 per unit. The demand for the product is uncertain but is estimated at 2,000 units for each year, 3,000 units for each year or 5,000 units for each year. (Note that whatever sales volume level actually occurs, that level will apply to each of the three years.)
The sales manager has placed probabilities on the level of demand as follows:
