To find the percentage increase in sales that would equal a 2.65% savings on purchase expenses, we can follow these steps:

1. Calculate the current purchase expenses: $\text{Purchase Expenses} = \text{Revenue} \times \text{Percentage of Revenue spent on Purchases}$ $\text{Purchase Expenses} = 6,750,000 \times 0.42 = 2,835,000$

2. Calculate the savings from the purchase expenses: $\text{Savings} = \text{Purchase Expenses} \times \text{Savings Percentage}$ $\text{Savings} = 2,835,000 \times 0.0265 = 75,097.50$

3. Determine the additional revenue required to match this savings in profit: Since the net profit margin is 12.75%, we can find the amount of sales needed to achieve the same profit increase: $\text{Required Increase in Revenue} = \frac{\text{Savings}}{\text{Net Profit Margin}}$ $\text{Required Increase in Revenue} = \frac{75,097.50}{0.1275} \approx 589,122.55$

4. Calculate the percentage increase in sales: $\text{Percentage Increase in Sales} = \frac{\text{Required Increase in Revenue}}{\text{Current Revenue}} \times 100$ $\text{Percentage Increase in Sales} = \frac{589,122.55}{6,750,000} \times 100 \approx 8.74\%$

Therefore, the company would need to increase sales by 8.74% to match the profit increase from a 2.65% savings on purchase expenses.
