Answer:
That a memorandum of understanding was created by the receipt sent by Mr. Blue and an
enforceable agreement exists
Step-by-step explanation:
A memorandum of understanding is an agreement between two or more parties stating a lone of action that is binding on the participants.
This is used in place of a legally enforceable agreement. Like a formal gentlemen's agreement.
In this instance they agree orally to transfer 500 widgets for $1,000. Mr. Blue sends Mr. Green a receipt one week after the agreement.
The act of sending a reciept establishes the fact that there is an agreement. Therefore it is enforceable in a court of law.
