Edith has 80 novels stuffed on her schoolbook shelf, half as many as the number of writing books she has stuffed in her suitcase. How many novels and writing books does Edith have altogether? Let's be accurate as possible.
Edith's number of writing books is 80 * 2 = 160, twice the number of novel books she has. Altogether, Edith has 160 + 80 = 240 books.
The answer: 240.
