Think in terms of Negotiable Instruments $($not the elements to form a contract$).$ All $7$ requirements are not present in each situation; however, identify which one is in question and if that appropriately qualifies it as an NI$.$ Provide a detailed explanation for each.

$1.$ Del and Ray, over lunch, discuss the purchase of an auto. Del, the buyer, tears a scrap off her brown lunch bag and writes terms down as Ray dictates. She signs it$.$ Assuming the terms are valid, does this qualify as a NI$?$

$2.$ Carl writes, "I promise to pay to the order of Kim Adams $$1,000$ if he replaces the roof on my garage." Does this qualify as a NI$?$

$3.$ A typed note provided the following: I Lindel Harper owe Randall Jansen $$30,000($thirty thousand dollars$)$ as of $9/27/99$ for the following:

$-$$$18000$ for Case backhoe

$-$$$5,000$ for a loan

$$7,000$ for a box trailer with hitch

Does this qualify as a NI$?$

$4.$ A note contains a promise to pay 'the value of savings bonds at maturity in $5$ years.$\text{'}$ Does this qualify as a NI$?$

$5.$ Bill creates a note today that says "Payable on December $30,2020"$ which is in only $4$ days. Does this qualify as a NI$?$
