To find the unit price of the red onions, you need to divide the total cost of the bag by the weight of the bag in pounds.
The total cost is $2.30, and the weight is 2 pounds.
Unit price = Total cost / Weight
Unit price = $2.30 / 2 lbs = $1.15 per pound
So, the unit price of the red onions is $1.15 per pound.
