</span>Question: Find the Unit rate for 108 diapers for
25.18 dollars.
Let’s analyze the given question. In a total of 108 diapers for 25.18 dollars.
Thus we need to find the amount of every 1 diaper then.
=> 108 diapers – is the total number of items
=> 25.18 dollars - the total amount
paid
=> Since we are looking for the price of each diapers, we need to divide the
amount with the number of diapers.
=> 25.18 / 108 = 0.23 dollars.
Thus the unit rate is 0.23 dollars/ diaper</span>
