To find the unit cost per candy bar, you need to divide the total cost by the total number of candy bars.
The correct process to use is:
350 divided by 1000
This will give you the cost per candy bar.
Let's do the calculation:
\[ \text{Unit Cost} = \frac{350}{1000} = 0.35 \]
So the unit cost per candy bar is $0.35.
