Tom read a book containing 480 pages by reading the same number of pages each day. If he would have finished the book 2 days earlier by reading 16 pages a day more, how many days did Tom spend reading the book?  Choose the correct choice from the following options.
A) 12	B) 15	C) 10	D) 20	E) 14
12ctually u can set up 2 equation   P--stands for the pages   D--stands for the days   1) P*D=480 (we want to find the Days, soP=480/D)   2) (P+16)(D-2)=480 =&gt; PD-2P+16D-32=480   as the 1) stated u can put 1) into 2)   =&gt; 480-2P+16D-32=480 =&gt; 16D-2P=32   put the bold one into it =&gt; 16D-2(480/D)=80   the we get the final equation 16D^2-960=80D (divide 16)   =&gt; D^2-5D-60=0   (D-12)(D+5)=0 so D=12 days 12ns: 12
