Answer:
because no nation's economy can produce all of the goods and services that it needs.
Explanation:
In simple words, International trade refers to the exchange of goods and services that occurs between the nations around the world for over all welfare and development of world economy.One of the major reasons behind such exchange is the opportunity cost of producing the same good differs among nations significantly.
For instance, a product that belongs to the labor intensive industry could be produced in India easily while as technology intensive good is feasible in America.Also due to difference of availability in natural resources some economies might not be able to produce some goods altogether.
Answer:
Yes this could be counted as GDP
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
