To find the unit cost of one orange, divide the total price of the bag by the number of oranges in the bag.
Here, the price of a bag of 8 oranges is $4.96.
Unit cost = Total cost / Number of oranges Unit cost = $4.96 / 8
Now doing the calculation:
\[ \text{Unit cost} = \frac{4.96}{8} = 0.62 \]
Therefore, the unit cost of one orange is $0.62.
