You can put this solution on YOUR website!
She read 1/4 of her book on Monday
Tuesday she read the rest, or 3/4 of the book
Let +p+ = number of pages she read on Monday
+80+%2B+p+ = number of pages she read on Tuesday
-----------
+p+%2B+80+%2B+p+=+80+%2B+2p+ = number of pages in book
+%283%2F4%29%2A%28+80+%2B+2p+%29+=+80+%2B+p+
+3%2A%28+80+%2B+2p+%29+=+4%2A%28+80+%2B+p+%29+
+240+%2B+6p+=+320+%2B+4p+
+2p+=+80+
+p+=+40+
++80+%2B+2p+=+80+%2B+2%2A40+
+80+%2B+2%2A40+=+160+
There are 160 pages in the book
