At the end of the month, the Accounts Receivable account had a balance of $3,130. What was the Accounts Receivable balance at the beginning of the month?

Please Provide how the problem is sloved and final numberic answer. Thank you.

Answer 1

Let x = the balance at the beginning of the month

x + 7,960. - 6,350. = 3,130.
x + 1,610. = 3,130.
x = 3,130. - 1,610.
x = 1,520. ANSWER

Check: If the account had 1,520. dr in the beginning, a 7,960. dr added to it would equal 9,480.
9,480. dr less 6,350. cr = 3,130. ending balance
