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.
