(2) in itself gives no real information, I had assumed (1) is true but I wrote it wrong earlier
If (1) and (2) are true
The most expensive book will be
16.999999…..9
Then 16.999999….8
And least exp will be 13.999999…..8
If you add the integer parts you get $45 and for the decimals all three are < 1 so sum < 3
Thus total 45 + decimals < 48
