Answer:
Estimated manufacturing overhead rate= $15 per direct labor hour
Explanation:
Giving the following information:
Overhead is allocated to each job based on the number of direct labor hours spent on that job.
The estimated overhead= $61,500.
Estimated direct labor hours= 4,100
To calculate the estimated manufacturing overhead rate we need to use the following formula:
Estimated manufacturing overhead rate= total estimated overhead costs for the period/ total amount of allocation base
Estimated manufacturing overhead rate= 61,500/4,100= $15 per direct tlabor hour
Solution:
Given Information,
Heat input is (
) = 5.5 ×
Btu/h
Combustion efficiency of the boiler (
) = 0.7
Combustion efficiency after turn up (
) = 0.8
Operation Hour (t) = 5200h
Unit cost (c) = 
Calculate heat output from the boiler
=
x 
= 5.5 x
x 0.7
= 3.85 x
Btu/h
Calculate the heat input to the boiler after the tune-up
=
/ 
= 3.85 x
/ 0.8
= 4.8125 x
Btu/h
Calculate the saved energy after the tune-up
=
- 
= 5.5 x
- 4.8125 x
Btu/h
= 0.6875 x
Btu/h
Calculate the annual energy saving (
)
=
x t
= ( 0.6875 x
Btu/h ) ( 5200 hr/yr)
= 3575 x
Btu/h
Calculate the annual cost saving
Annual cost saving =
x Unit cost
= 3575 x
Btu/h x 
= 82225
Answer: A. Lowering the degree of operating leverage.
Explanation:
The degree of operating leverage measure how much the earnings from a project will change as a result of sales.
If you are worried about the cash flow forecasts, it would be best to lower the operating leverage so as to reduce the forecasting error associated with the project. If the operating leverage is high then a small change in sales could impact income in a relatively huge way. By reducing the DOL, the cashflow from the project is easier to forecast and therefore more reliable.
