**Reiny**, Monday, February 18, 2008 at 9:51pmAhhh, great question!!!!

We know two of the prices, the high and the low, which is a total of $43.

So the average price of the remaining 19 books must be > $18 and < $25

(375-43)/19 = 17.5 no good

(530-43)/19 = 25.6 no good

(175-43)/19 = 6.9 no good**(445-43)/19 = 21.1 YUP!, that's it.**
