During the first 11 months of a recent year, a certain charitable organization received an average (arithmetic mean) of $20,600 per month in donations. how much did the organization receive in donations during december of that year if the average amount of donations per month for the entire year was $21,000 ?

$25,400

Explanation:

Average for first 11 months = $20,600

Total amount for first 11 months = 11 x $20,600 = $226,600

Average for 12 months = $21,000

Total amount for 12 months = 12 x $21,,000 = $252,000

Amount received in December =  $252,000 - $226,600 = $25,400

The organization received $25,400 in donations during December
