On the eve of the Spring Festival, a store, based on market research, spent 2000 yuan to purchase the first batch of boxed flowers. After they were put on the market, they were quickly sold out. Then, the store spent 4200 yuan to purchase the second batch of these boxed flowers. It is known that the number of boxes in the second batch is three times that of the first batch, and the cost price per box of flowers is 6 yuan less than that of the first batch.
