Answer: 4,000 units per day.
Explanation:
You know that in 2001 its yearly volume was 50% of its volume for 2004.
Therefore, if in 2001 the company marketed 730,000 units of its product, in 2004 the volume is:
![Yearly\ volume_((2004))=(730,000\ units)(2)=1,460,000\ units](https://img.qammunity.org/2020/formulas/mathematics/middle-school/15lzrz5k0x5sluxdne0zx0hwnsaxlvsrsn.png)
Let be "x" the number of units for each of the 365 days of 2004, you can find its value by dividing the 2004 volume by 365.
The result is:
![units=(1,460,000\ units)/(365)=4,000\ units.](https://img.qammunity.org/2020/formulas/mathematics/middle-school/p90joe91kblaazrmsxoupc0njc4fnl3hsl.png)
