Depreciation Calculation:

The machine is worth 490,740. It is depreciated at 15% on its opening value each year.

To calculate the depreciation each year, we can use the following formula:

Depreciation = Opening Value * Depreciation Rate

Year 1:
Depreciation = 490,740 * 15% = 73,611

The machine's value after the first year would be:
Value after Year 1 = Opening Value - Depreciation
Value after Year 1 = 490,740 - 73,611 = 417,129

Year 2:
Depreciation = 417,129 * 15% = 62,570

The machine's value after the second year would be:
Value after Year 2 = Value after Year 1 - Depreciation
Value after Year 2 = 417,129 - 62,570 = 354,559

Year 3:
Depreciation = 354,559 * 15% = 53,184

The machine's value after the third year would be:
Value after Year 3 = Value after Year 2 - Depreciation
Value after Year 3 = 354,559 - 53,184 = 301,375

Year 4:
Depreciation = 301,375 * 15% = 45,206

The machine's value after the fourth year would be:
Value after Year 4 = Value after Year 3 - Depreciation
Value after Year 4 = 301,375 - 45,206 = 256,169

Year 5:
Depreciation = 256,169 * 15% = 38,425

The machine's value after the fifth year would be:
Value after Year 5 = Value after Year 4 - Depreciation
Value after Year 5 = 256,169 - 38,425 = 217,744

Year 6:
Depreciation = 217,744 * 15% = 32,661

The machine's value after the sixth year would be:
Value after Year 6 = Value after Year 5 - Depreciation
Value after Year 6 = 217,744 - 32,661 = 185,083

Year 7:
Depreciation = 185,083 * 15% = 27,762

The machine's value after the seventh year would be:
Value after Year 7 = Value after Year 6 - Depreciation
Value after Year 7 = 185,083 - 27,762 = 157,321

Year 8:
Depreciation = 157,321 * 15% = 23,598

The machine's value after the eighth year would be:
Value after Year 8 = Value after Year 7 - Depreciation
Value after Year 8 = 157,321 - 23,598 = 133,723

Year 9:
Depreciation = 133,723 * 15% = 20,059

The machine's value after the ninth year would be:
Value after Year 9 = Value after Year 8 - Deprec
