Five Transactions 

Oct. 1 Dr. Rex Arnold opened his practice by investing $30,000 cash in his business. 

        2 Purchased $17,000 of office equipment on account from Medical Products, Inc. 

        18 Paid $7,000 on account to Medical Products, Inc. 

        20 Received $3,500 of fees earned in October. 

        30 Paid monthly salaries of $1,500. 

My answer was $56,500=$13,500+$14,500 but not sure if it’s correct. Thank you
