Answer: $1.637; $1.404
Explanation:
Given that,
Last year:
Output - Sales = $200,100
Input:
Labor = 30,100
Raw materials = 35,100
Energy = 5,010
Capital = 50,010
Other = 2,010
Input = 30,100 + 35,100 + 5,010 + 50,010 + 2,010
= 122,230
Total Productivity = 
= 
= $1.637
This year:
Output - Sales = $202,100
Input:
Labor = 40,100
Raw materials = 45,100
Energy = 6,050
Capital = 49,750
Other = 2,875
Input = 40,100 + 45,100 + 6,050 + 49,750 + 2,875
= 143,875
Total Productivity =
= 
= $1.404

Answer: 10 months
Explanation:
It would take the Hendersons 10months to recover their cost if they decide to do it themselves over the professional service.
Here is how;
Doing it themselves would cost -
$250 - For a lawnmower
$135 - For an edger
$69 - For a hedge trimmer
$25 - For a rake
Summing these up gives $479
It would cost the Hendersons $479 to purchase equipments to carry out their monthly yard maintenance themselves.
On the other hand, if they were to hire a professional service, it would cost
• $75 for the first month and
• $45 for subsequent months
So, $45 * 9months = $405
$405 + $75 (for the initial month) = $480
Comparing the $480 for a professional to the $479 it would cost to purchase equipment and do it themselves, it would take the Hendersons 10months to recover their cost if they decide to do it themselves over the professional service.
