Answer:
b. $105,000
Explanation:
Beginning allowance for uncollectible accounts = $180,000
Uncollectible written off = $210,000
Allowance for the year 20X7 = Credit sales * 3%
                        = $4,500,000 * 3%
                        = $135,000
Allowance for uncollectible accounts = $180,000 - $210,000 + $135,000
= $105,000
Therefore, The amount that Gear should report as allowance for uncollectible accounts is $105,000.
