Solution
To find the average cost per book for each brother, we need to divide the total cost of the books by the number of books each brother bought.
For Ty: 14.24 per book
For Cam: 15.47 per book
To find out who paid more on average, we subtract the smaller average cost from the larger one:
14.24 = $1.23
So, Cam paid an average of $1.23 more per book than Ty.
