Moonlight Industries just signed a sales contract with a new customer. JK will receive annual payments in the amount of $$50,000,$ $$96,000,$ $$123,000,$ and $$138,000$ at the end of Years $1$ to $4,$ respectively. What is this contract worth at the end of Year $4$ if the firm earns $3\mathrm{.}75$ percent on its savings?
