XYZ had stock returns of -0.05, 0.44, -0.28, 0.18 over the past 1 yr. What is XYZ's cumulative return over that time period

Date                 Account Title                                         Debit             Credit

Jan, 2               Cash                                                       $100

                         Accounts Receivable                           $700

                        Service revenue                                                        $800

$100 will be debited to Cash to show that $100 was received. The rest of the bill will go to the Accounts Receivables to shows that it is still owed. Then finally the entire $800 will go to Service revenue to show that services were performed for a client up to $800 worth.
