Let the maximum number of pages Jennifer can have be = x

Amount Jennifer has (P) = $62.10

Given equation is :

P = $(20+0.5x)+0.15(20+0.5x)$

Price is given = 62.10 , so equation is :

$62.10=(20+0.5x)+0.15(20+0.5x)$

$62.10=20+0.5x+3+0.075x$

$62.10=23+0.575x$

$0.575x=39.10$

$x=68$

Hence, Jennifer can have a maximum of 68 pages in her book.
