I had a similar issue with this assignment. There are definetly items missing from the problems themselves. On June 16 Purchased merchandise for Shelby Manufacturing is missing the proper credit terms. It's showing 10, n/30 when it should read either 1/10, n/30 or 2/10, n/30 etc..
Also for June 17 showing just recieved goods from Shelby.. There is info missing. I've emailed this to student services..hopefully they will correct it soon.
