Answer:
E started with 26 books, sold 13 books, bought 17 more books, and ended with 30 books
Step-by-step explanation:
E has _ books: x
E Sells 1/2 of that _ books: x/2
E buys 17 books and now had 30: (x/2) + 17 = 30
30 - 17 = 13
13 x 2 = 26
x/2 = 26
13 + 17 = 30 <-- checking work
My guess is that x = 13
