The unitary method is a method in which you find the value of a unit and then the value of a required number of units.
According to the given question.
The amount of money Madeline have = $18.

Cost of one bottle mineral water = $2.75
⇒ Cost of two mineral water bottle = 2 × $2.75 = $5.5
Amount of money left = $18 - $5.5 = $12.5
Therefore, the number of bags of popcorn Madeline can buy from $12.5
= [tex]\frac{12.5}{3.50}[/tex]
[tex]=3.57[/tex]
