ER Medical Supplies had sales of 2,000 units at $160 per unit last year. The marketing manager projects a 25 percent increase in unit volume this year with a 10 percent price increase. Returned merchandise will represent 5 percent of total sales. What is your net dollar sales projection for this year?

To calculate the net dollar sales projection for this year, we need to consider the increase in unit volume, the price increase, and the percentage of returned merchandise. Here is how you can calculate it step by step:

1. Calculate the projected increase in unit volume:
- The marketing manager projects a 25 percent increase in unit volume.
- Multiply the current unit volume by the projected percentage increase: 2,000 units * 25% = 500 units.
- Add the projected increase to the current unit volume: 2,000 units + 500 units = 2,500 units.

2. Calculate the projected price per unit:
- There is a 10 percent price increase.
- Calculate the price increase amount: $160 * 10% = $16.
- Add the price increase to the current price per unit: $160 + $16 = $176.

3. Calculate projected total sales:
- Multiply the projected unit volume by the projected price per unit: 2,500 units * $176/unit = $440,000.

4. Calculate returned merchandise:
- Returned merchandise represents 5 percent of total sales.
- Calculate the returned merchandise amount: $440,000 * 5% = $22,000.

5. Calculate the net dollar sales projection:
- Subtract the returned merchandise amount from the projected total sales: $440,000 - $22,000 = $418,000.

Therefore, the net dollar sales projection for this year is $418,000.
