Answer:
See below
Step-by-step explanation:
Estimated uncollectible based on past experience
= [($1,800,000 × 60%) × 0.5%]
= $1,080,000 × 0.5%
= $5,400
Credit balance in allowance for doubtful account = $2,000
Therefore, the total amount M should report as its estimated bad debts expense for the year 2018
= $5,400 - $2,000
= $3,400
