Final answer:
A new computer costing $540 would depreciate by 20% in the first year, which is calculated as $540 multiplied by 0.20, resulting in a depreciation value of $108.
Step-by-step explanation:
The value of a computer depreciates by 20% each year. To find out how much a new computer that costs $540 would depreciate in the first year, we calculate 20% of $540.
Depreciation = Original Cost × Depreciation Rate
Depreciation = $540 × 0.20
Depreciation = $108
Therefore, a new computer costing $540 would depreciate by $108 in the first year.
