Answer:
The answer is: Will increase the asset value by $6,000 (total asset value $24,000) and record depreciation expenses by $3,000 per year (for 8 years of remaining useful life)
Step-by-step explanation:
The value of the asset modified will change from $18,000 (the difference between $30,000 original cost minus $12,000 depreciation) to $24,000 including the repairs.
The depreciation expense can be calculated by dividing the new asset value ($24,000) by the new useful life of the asset (8 years) to $3,000 per year.
