Answer:
the UCC because it is a mixed contract predominately for the sale of goods.
Explanation:
The Universal Commercial Code deals with transactions that involve goods. Goods are defined as anything that is moveable including specially manufacturerd goods that is part of the contract of sale.
When there is a mixed transaction involving goods and services we consider the predominant transaction.
For transactions that are predominantly for purchase of goods with an additional service for example installation, is considered to be for goods and is handled by the UCC.
If the transaction is predominantly for services then it is not handled by UCC.
Dilian is purchasing trees so this is the predominant transaction. He will also get a service to install the trees this is the minor or added part of the transaction.
