Final answer:
The amount of uncollectible accounts expense shown on the Year 3 income statement is $8,800.
Step-by-step explanation:
The amount of uncollectible accounts expense shown on the Year 3 income statement can be calculated by determining the ending balance in the allowance for doubtful accounts account. To find this balance, we start with the beginning balance of $1,400 and add the estimated amount of uncollectible accounts for the year. Since Omega estimates uncollectible accounts to be 4% of receivables, we can calculate the estimated uncollectible accounts as $220,000 * 0.04 = $8,800. Therefore, the ending balance in the allowance for doubtful accounts account is $1,400 + $8,800 = $10,200.
The uncollectible accounts expense shown on the Year 3 income statement is the increase in the allowance for doubtful accounts from the beginning balance to the ending balance. Therefore, the uncollectible accounts expense is $10,200 - $1,400 = $8,800.
