Ms. Rodríguez plans to order from 20 to
26 books for her class. The prices of the books
she plans to order range from $4.95 to $12.95
each. If the publisher charges a shipping fee of
$0.50 per book ordered, which of the following
is not a reasonable price for the books,
including shipping?
The answer is 445, how do I solve for this?

The maximum possible price is for 26 books, each costing the maximum of $12.95 + $0.50 shipping,
= 26 x ($12.95 + $0.50)
= 26 x ($13.45)
= $349.70
So any price over $349.70 is not possible. (Or not "reasonable" as your question puts it).
