A machine has an investment cost of $60,000 at time 0. The present values (at time 0) of the expected net cash inflows from the machine over its useful life are：
Discount rate Present value of cash inflows
10% $64,600
15% $58,200
20% $52,100
What is the internal rate of return (IRR) of the machine investment?
$
Investment (60,000)
PV of cash inflow 64,600
NPV @ 10% 4,600
$
Investment (60,000)
PV of cash inflow 58,200
NPV @ 15% (1,800)
The IRR of the machine investment is therefore between 10% and 15% because the NPV falls from $4,600 at 10% to -$1,800 at 15%. Therefore at some point between 10% and 15% the NPV = 0. When the NPV = 0, the internal rate of return is reached.

A company uses a standard absorption costing system. Last month budgeted production was 8,000 units and the standard fixed production overhead cost was $15 per unit. Actual production last month was 8,500 units and the actual fixed production overhead cost was $17 per unit.What was the total adverse fixed production overhead variance for last month?
A cost centre had an overhead absorption rate of $4.25 per machine hour, based on a budgeted activity level of 12,400 machine hours.In the period covered by the budget, actual machine hours worked were 2% more than the budgeted hours and the actual overhead expenditure incurred in the cost centre was $56,389.What was the total over or under absorption of overheads in the cost centre for the period?
Which of the following would help to explain a favourable direct labour efficiency variance?
