Answer:
$7,000
Step-by-step explanation:
The previous balance of the allowance for uncollectible accounts was $4,000, then $3,000 were written off, so the new balance = $4,000 - $3,000 = $1,000
if current sales are estimated at $150,000 and 4% will be uncollectible, then you should add $150,000 x 4% = $6,000 to the allowance for uncollectible accounts.
The current account balance should be $1,000 + $6,000 = $7,000
