Answer:
$5.50 / 2 = $2.75
Explanation:
Unit price - A unit price is the price of 1 item.
In this question, we have 2 cartons of milk and altogether it costs $5.50. So in order to find the price for 1 milk carton (unit price) then we need to divide 5.50 by half. So, 5.50 / 2 = 2.75
CHECK:
2.75 x 2 = 5.50 :)
