Evans used his credit card to run up a $98.75 bill with the Rosen Department Store. When Rosen tried to collect, Evans wrote a check for $79.00. He wrote on the check that he meant it to be "full payment of all accounts to date." Rosen cashed the check.
When Rosen sued Evans for $19.75 balance, Evans argued that under accord and satisfaction, the fact that Rosen cashed the $79.00 check meant that it had accepted that amount as full payment. Was Evans correct? Explain.
