If the total price for \(n\) copies of a book is $31.50, what is the price per copy of the book?
(1) If twice as many copies were bought for the same total price, the price per copy would be $1.75.
(2) If 4 fewer copies were bought for the same total price, the price per copy would be $2.80 greater.
