To solve the problem of determining the unit cost per candy bar, you should use the division process. Specifically, you will divide the total cost by the number of candy bars.
The correct process is:
350 ÷ 1000 (350 divided by 1000).
Now, to calculate the unit cost:
- Divide the total cost by the number of candy bars: \[ \text{Unit cost} = \frac{350}{1000} = 0.35 \]
Thus, the unit cost per candy bar is $0.35.
