Information related to accounts receivable is given for two cases: Case 1 Zed Corporation used the credit sales method to estimate bad debt expense. In 2022, credit sales totaled $1,305,000 for the year. The ending balance of A/R in 2022 is $191,250 (which is already adjusted for $14,100 written off during the year after it was deemed uncollectible). The opening balance of the allowance for doubtful accounts in 2022 was $20,400. Over time, 0.75% of credit sales have been uncollectible. Case 2 Modern Technology Limited reported an unadjusted balance of accounts receivable of $3,750,000 at 31 December 2022, along with a credit balance in the allowance for doubtful accounts of $151,000. At year end, they decided that $160,400 of accounts receivable were uncollectable and should be written off. Of the remaining receivables, it was determined that 45% were current, and of the remaining net current balance, an allowance for doubtful accounts of 2.5% of the net balance was needed. The remaining 55% of outstanding accounts receivable were past due and an allowance for doubtful accounts of 15% of the outstanding balance was needed. Required: For each case above, calculate the a) allowance for doubtful account and net receivable balance that would be reported on the statement of financial position, as well as b) the bad debt expense for the year
