To find the unit rate, you need to divide the total number of orders by the number of days.
Given:
- Total orders = 78
- Total days = 3
Now, calculate the orders per day:
\[ \text{Orders per day} = \frac{\text{Total orders}}{\text{Total days}} = \frac{78}{3} = 26 \]
So, the unit rate is 26 orders per day.
