There are four gray rectangles in the graph, showing 2 different probabilities. Add together the areas of the two rectangles located on the right side:
0.35+0.05 = 0.40 (answer)
First you divide $4000 by 160 to see how much each book costs. Then you multiply 2 times the cost for each book and subtract that from $4000.
$4000/160= $25
$25=1 book
So if the store gives away 2 books that's $50 dollars. $4000-$50 equals 3,950
