<h3>What is Unitary method?</h3>
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value. 
Given:
spend on materials = 220
Price for each flower =10.50
If 23 flowers are sold price would be,
= 10.50*23
=241.5
Hence, the profit would be = 241.5-220
                                              = $21.5
