Answer:
7.4%
Step-by-step explanation:
As we know that
ROE = Profit margin × Total asset turnover × Equity multiplier
where,
Profit margin = (Net income ÷ Sales) × 100
= ($10,000 ÷ $200,000) × 100
= 5%
So, the ROE would be
= 5% × 1.60 × 1.85
= 14.8%
Now if the net income is increased by $5,000
So, the updated profit margin would be
= (Net income ÷ Sales) × 100
= ($15,000 ÷ $200,000) × 100
= 7.5%
And updated ROE would be
= 7.5% × 1.60 × 1.85
= 22.2%
So, the change in ROE would be
= 22.2% - 14.8%
= 7.4%
