The marginal product of labor eventually slopes downward due to diminishing marginal costs diminishing average returns diminishing marginal utility the law of diminishing marginal productivity

The marginal product of labor eventually slopes downward due to the law of diminishing marginal productivity. The law of diminishing marginal productivity is a principle within economics. This principle states even if you increase input in one area and keep the others the same, output does increase, there will be limited effect and eventually balance back out resulting in no effect on the output. 

$1050 Using the aging method

Explanation:

$10,000 of accounts receivable that are current

$5,000 that are between 0 and 30 days past due

$3,000 that are between 30 and 60 days past due

$800 that are more than 60 days past due.

The percentages of the following accounts will be uncollectible

2% of $10000 are uncollectible=$200

5% of $5,000=$250

10% of 3000=$300

50% of $800=$400

the sum of the uncollectible is $1150

Note: Blain’s allowance for doubtful accounts account has a $100 positive balance.

so $1150-$100=$1050
