You have been pricing Samsung$-$Galaxy SmartWatch in several stores. Three stores have the identical price of $$200.$ Each store charges $12$ percent APR, has a $30-$day grace period, and sends out bills on the first of the month. On further investigation, you find that store A calculates the finance charge by using the average daily balance method, store B uses the adjusted balance method, and store C using the previous balance method. Assume you purchased the SmartWatch on May $5$ and made a $$100$ payment on June $15.$

What will the finance charge for June be if you made your purchase from store A$?$ From store B$?$ From store C$?$
