6.57. Sisters Ania and Jola sell tulips in spring in different parts of town. One day they divided 70 tulips among themselves so that Ania got x tulips and Jola y tulips. Each of them set a different price for 1 tulip. After selling all the flowers it turned out that both girls received the same amount. If Anna had sold y tulips, she would have received 45 USD. If Jola had sold x tulips, she would have received 80 USD. Calculate how many tulips Ania sold and how many Jola sold. At what price per piece did Anna and Jola sell tulips?
