Answer:
a.  Labor Cost Rate=   13 $ per DLH
b.  Purchase orders Rate= $ 3 per order
c. Product testing Rate =   $ 15 per test
d. Template etching Rate = $ 23 per template
e. General factory Rate=   $ 6 per MHs
Explanation:
Data
Activity            Activity                Expected Overhead       Expected 
Cost Pool      Measure                  Cost                              Activity
Labor-related Direct labor-hours $16,380                 1,260 DLHs
Purchase orders Number of orders $1,920                 640 orders
Product testing Number of tests    $4,275                285 tests
Template etching Number of templates $805          35 templates
General factory Machine-hours          $42,600            7,100 MHs
The activity rate can be obtained by dividing the  total cost of each activity with the total cost of the driver allocated to it.
Calculations
Activity Rate = Expected Overhead Cost/ Expected Activity 
a.  Labor Cost Rate=   $16,380   /  1,260 DLHs=  13 $ per DLH
b.  Purchase orders Rate=  $1,920/  640 orders= $ 3 per order
c. Product testing Rate =  $4,275 /285 tests= $ 15 per test
d. Template etching Rate = $805 /35 templates= $ 23 per template
e. General factory Rate=  $42,600/ 7,100 MHs= $ 6 per MHs
