1. On October 15, WTI agreed to teach a four-month class (beginning immediately) for an individual for $3,240 tuition per month payable at the end of the class. The class started on October 15, but no payment has yet been received. (WTI's accruals are applied to the nearest half-month; for example, October recognizes one-half month accrual.)

I believe the answer is

Accounts receivable 8100

Accounts Payable 8100

It says my answer is incorrect even thought it says no payment has yet been recieved.
