* The creator sold 1500 per day for the first 15 days.
* So for the first 15 days she sold 1500 * 15 = 22,500 units
* For the next 15 days she sold 2070 per day
* So for the next 15 days she sold 2070 * 15 = 31,050 units
* In total over 30 days she sold 22,500 + 31,050 = 53,550 units
* To find the average per day over 30 days, divide the total by 30:
* 53,550 / 30 = 1,785
Therefore, the average number of units she sold per day over the entire 30 days is 1,785.
