Final answer:
The unit rate for oranges is $0.50 for one orange. Therefore, the correct option is C) $0.05 for one orange
Step-by-step explanation:
The unit rate refers to the cost of one item or unit. In this case, it is the cost of one orange. To find the unit rate, we divide the total cost of the oranges by the number of oranges. If oranges cost $6.00 for a dozen (12), then the unit rate is $6.00 divided by 12, which equals $0.50 for one orange.
