Answer:Yes, helping her grandmother provided consideration.
Step-by-step explanation:
Consideration is anything of legal value that one party offers in exchange of another thing. For example Laura offers Sally a right to be an heir to her house if she comes and take care of her which Sally did. This is an obligation that Larry commited to and the consideration is valid since Sally did offer her service to her grandmother as an exchange to her recieving ownership of her home. Each party is required to commit to their consideration as part of an agreement of which Sally did her part and now Laura's obligation need to be fulfilled as per agreement.
There are two types of considerations:
Valuable consideration is promise of exchange that involves money.
Good consideration these are other valuables apart from money.
Both these type of consideration are legally enough to enforce someone to abide by a contract. The law doesn't weigh the quality of what each party exchanged even if they may not be of equal value but its considers the fact both parties might have thought it all through and felt it was fair agreement.
