Answer:
(20/45 x $30) + (25/45 x $15) = $21.66
Step-by-step explanation:
Since the contract is modified and the additional 25 products are priced at $15 each, a price that is not reflective of the standalone selling price.
Therefore the price will be shown as a blending of the existing price of $30 because it is not entirely a new contract but a modification
The price per product for the remaining 45 products (20 products from the original contract and 25 products from the modification) will be:
(20/45 x $30) + (25/45 x $15) = $21.66
