Data inc. offers to provide certain services to enterprise llc, but mistakenly transposes some of the digits in the price so that $15,400 appears in the offer as $14,500. enterprise accepts the written offer. enterprise’s best argument in favor of enforcement of the contract is that:

A unilateral mistake does not invalidate a contract. Data made a unilateral mistake by charging more money than usual to Enterprise, but Enterprise accepted that offer. That means that the contract is enforceable. In this case Data got more money but if the mistake would have been different (e.g. they offered $10,450 instead of $14,500) then Data should perform their part and lose money.

Only if the unilateral mistake was really important to the consideration of the contract, can the contract be voided, but this is not the case. For example, a mistake is made when stating a house's address, that would be important enough to void the contract.
