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.

The line represented by the equation 3x + 5y = 2 has a slope of -3/5 the look of the graph
DiKsa [7]
<span>3x + 5y = 2 can be solved for 5y and then for y:  5y = -3x + 2, and so

y = (-3/5)x + 2/5.  Slope is -3/5 and y-intercept is (0, 2/5).  If you want more info, please ask specifically for what you want.
