Answer:
Dr supplies expense $1,500
Cr supplies inventory $1,500
Step-by-step explanation:
Firstly,when the balance of the supplies on hand at March 1 2020 is added to supplies purchased,the total is $1700 ($500+$1200).
However,the usage of $1,500 worth of supplies for the month of March implies that the supplies has gone down by $1,500,in essence the main task is to effect the usage in the books of accounts.
The appropriate adjusting journal entry would be to credit supplies inventory account with $1,500 and debit supplies expense account with the same amount.
