Answer:
$1.51
Explanation:
Unit price represents the cost of only one item.
To find our answer:
Divide $4.53 by 3, to represent the cost of one kg. bag of red onions.
4.53 / 3 = 1.51
Check:
(One kg. bag) $1.51 x 3 (Represents the number of bags given)
= $4.53
The unit price of a 3-kg. bag with the cost of $4.53, is $1.51 per one kg.
