 
 <translate> On Sunday they sold twice as many books in - store as the 37 books on Saturday so they sold 2 * 37 = 74. They sold 128 books online on Saturday and increased that number by 34 books on Sunday for a total of 128 + 34 = 162. Over the weekend they sold 37 + 128 + 74 + 162 = 401 books. They started off with 743 books and sold 401 books which brings the inventory to 743 - 401 = 342 books. They have 342 books and received a shipment for 160 bringing their inventory to 342 + 160 = 502 books.
Thus, the answer is 502. <hau> A ranar Lahadi sun sayar da littattafai sau biyu a cikin shagon fiye da littattafai 37 a ranar Asabar don haka sun sayar da 2 * 37 = 74.
