Answer:
the depreciation expense increased by 50% during the current year.
Explanation:
Current Year Prior Year % change
Sales $120,000 $100,000 +20%
Cost of Goods Sold $80,000 $60,000 +33.33%
Depreciation Expense $30,000 $20,000 +50%
Interest Expense $2,000 $5,000 -60%
Even though the interest expense changed in a higher percentage (-60%), the question asked for which item increased the most, but the interest expense decreased.
