A manufacturer of insulation panels expands its annual output to 500,000 panels. It keeps a £4 million loan throughout the year.
Table 1 shows changes following the expansion.
| Item | Before expansion | After expansion |
|---|---|---|
| Interest rate on the loan | 7.0% | 4.5% |
| Additional annual management and administration costs | £0 | £140,000 |
Assume that all other costs are unchanged.
Calculate the change in average cost per panel caused by the lower interest rate and the additional management and administration costs.
