 
 <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. <ibo> N'ụbọchị Sọnde, ha rere akwụkwọ n'ụlọ ahịa ahụ okpukpu abụọ karịa akwụkwọ iri atọ na asaa ha rere n'ụbọchị Satọdee, n'ihi ya, ha rere akwụkwọ iri asaa na anọ. Ha rere akwụkwọ 128 na ntanetị na Satọde ma mụbaa ọnụ ọgụgụ ahụ site na akwụkwọ 34 na Sọnde maka ngụkọta nke 128 + 34 = 162. Na ngwụsị izu ha rere akwụkwọ 37 + 128 + 74 + 162 = 401. Ha bidoro na akwụkwọ 743 ma ree akwụkwọ 401 nke na-eweta ngwongwo na 743 - 401 = 342 akwụkwọ. Ha nwere akwụkwọ 342 ma nata akwụkwọ 160 nke na-eweta ngwongwo ha na 342 + 160 = 502 akwụkwọ. N'ihi ya, azịza ya bụ 502.
