You have been pricing a compact disk player in several stores. Three stores have the identical price of $300. Each store charges 18 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 uses the previous balance method. Assume you purchased the disk player on May, 5 and made a $100 payment on June 15. What will the finance charge be (for June) if you made you purchase from store A? From store B? From store C? (Do not round your intermediate calculations and your answers to 2 decimal places.)
