hi can you help me calculate bad debt expense with an allowance of 1400, account receivable of 13600. 5000 is over due and they expect 20% will be noncollectable and the rest would be 5% noncollectable. i calculated the math to be 1430 since 20% of 5000 is 1000 and 5% of 8600 is 430, and i think i am suppose to subtract the allowance from the 1430 and then in the journal entry i would put 30 debited to bad debt, but i keep only getting the amount wrong on my hw.
