<PRE><B>Question 1121091</B>
each clerk earns 10 dollars an hour and works 8 hours a day.


each of these clerks can produce 50 entries a day.


50 / 8 = 6.25 entries an hour for each clerk.


when they work together, they make a combined 20 dollars an hour and can produce 12.5 entries for each hour.


500 / 12.5 = 40 hours.


40 hours * 20 dollars an hour = 800 dollars.


the total cost to produce 500 entries is 800 dollars.
