Peter obtains his supplies from Janus. An invoice for the amount of $240,000 was issued on 30 April. The amount is due on 14 May. Janus' standard terms of agreement state that in the event of a delay in payment, liquidated damages in the amount representing 10% amount of the invoiced amount will be added on to the total amount payable every week. Peter paid the

invoiced amount on 29 June, but Janus insists on enforcing the liquidated damages clause. Advise Peter.
