Answer:
Option (A) is correct.
Explanation:
Accounts receivable as on 12/31/2016 = $218,000
A/R as on 12/31/2017:
= Accounts receivable as on 12/31/2016 + Increase in A/R
= $218,000 + $22,400
= $240,400
uncollectible accounts = 3% of accounts receivable
                   = 0.03 × $240,400
                   = $7,212
Allowance 12/31/2016 = $8,800
Writes Off = $7,650
Therefore,
Allowance = Allowance 12/31/2016 - Writes Off
         = $8,800 - $7,650
         = $1,150
Hence,
Bad debt expense for 2016 = uncollectible accounts - Allowance
                       = $7,212 - $1,150
                       = $6,062
