Answer:
Nigeria employs a combination of tariffs and quotas for the double purpose of taxing international trade for revenue generation and protecting local industries from highly competitive imports. The country's tariffs are determined by the ECOWAS 2015 – 2019 Common External Tariff (CET) Book.Sep 14
Explanation:
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:
0.0642 or 6.42%
Explanation:
The period 't' between the year when the coin was issued, 1794, and 1971 is:

If the coin had a value of $5 and after a period of t=177 years it was worth $305,000, the annual tax rate by which the coin appreciated is determined by:
![305,000 = 5*(1+r)^{177}\\r=\sqrt[177]{61,000}-1\\r=0.0642=6.42\%](https://tex.z-dn.net/?f=305%2C000%20%3D%205%2A%281%2Br%29%5E%7B177%7D%5C%5Cr%3D%5Csqrt%5B177%5D%7B61%2C000%7D-1%5C%5Cr%3D0.0642%3D6.42%5C%25)
The annual rate was 0.0642 or 6.42%.
Contributions shall be paid until contributions for eligible spending are removed.
<u>Explanation:
</u>
A Flexible Spending Account (FSA) is a kind of savings account that offers specific tax incentives for the account holder. The employer for a contractor provides the FSA, also known as a flexible spending plan. The account requires workers to pay for eligible charges related to medical care and dentistry for a percentage of their daily earnings.
An FSA is a form of savings account that helps workers to pay for authorized expenses in a part of their regular income.
Funds paid to the company shall, due to payroll deductions, be excluded from the worker’s wages.
The money must be invested by the completion of the scheme year in the FSA, but employers can give up to 2.5 months of time until 15 March next year.
