The maximum capacity of the specialist machine for next year is limited to 6,000 hours.

2. Calculate the maximum amount it would be worth the firm paying per hour, to rent an additional specialist machine.
3. Other than renting a specialist machine, what could More Limited do to solve the problem of shortage of specialist machine time?
4. Critically discuss the use of marginal costing and absorption costing in the decision making process
