Answer:
The journal entry to record the purchase of the laundry supplies
June 2, laundry supplies purchased
Dr Laundry supplies inventory 10,030
Cr Cash or accounts payable 10,030
June 30, adjusting entry to record laundry expenses
Dr Laundry expenses 8,260
Cr Laundry supplies inventory 8,260
The initial inventory of laundry supplies is $10,030 and if at the end of the month only $1,770 worth of supplies are left, it means that $8,260 (= $10,030 - $1,770) were used.
