According to the question the cost of the book is $45.58
Money given by Joe is three $20 bills and three pennies.
So, total amount given by Joe to the cashier is = $60 + $0.03
= $60.03
Therefore the amount of change that Joe should get back is = Total amount given by Joe to cashier - Cost of book
= $60.03 - $45.58
= $14.45
"Joe will get $14.45 back". (Answer)
