Abookstore had 96 copies of a magazine. yesterday, it sold 1/3 of them. today, it sold 1/8 of what remained. how many copies does the bookstore have left?

The total number of magazine copies that the bookstore has is 96.
On the first day, the bookstore sold 1/3 copies ofmagazine among the total of 96.
Then the number of magazines sold on the yesterday = 96 * (1/3)
                                                                                   = 32
Number of magazines left in the bookstore now = 96 - 32
                                                                             = 64
So the bookstore sold 23 magazines on the yesterday.
Number of magazines sold by the bookstore today is 1/8 of the total magazines left.
Then the number of magazines sold today by the bookstore = 64 * (1/8)
                                                                                                 = 8
Then the number of copies that the bookstore has left = 64 - 8
                                                                                       = 56
