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:
the six month euro interest rate is 1.36%
Explanation:
Spot exchange rate: 1.4 USD/ EUR
6 month forward rate: 1.3950 USD/EUR
Domestic interest rate: 1% pa
Foreign interest rate: the six month euro interest rate?
We have the formula:
Forward rates = Spot rate * (1+domestic interest rate)/(1+foreign interest rate)
⇔ 1.3950 = 1.4 *(1+1%)/(1+foreign interest rate)
⇔ 1+foreign interest rate = 1.4 *(1+1%)/1.3950
⇔foreign interest rate = 1.01362 - 1 = 0.01362
⇒ the six month euro interest rate is 1.36%

Answer:
B) John can expect to earn $120,000 in revenue more by expanding, but that is less than the cost of expansion, $150,000.
Explanation:
If John decides not to expand his expected revenue will be = ($100,000 x 50%) + ($300,000 x 50%) = $50,000 + $150,000 = $200,000
If John decides to expand his expected revenue will be = ($100,000 x 30%) + ($300,000 x 30%) + ($500,000 x 40%) = $30,000 + $90,000 + $200,000 = $320,000
If John decides to expand, his revenue will increase by $120,000.
Since we are not told if John's revenue is yearly or not, I assume that it includes a whole business or project cycle. The cost of expanding is $150,000 while the incremental revenue is only $120,000.
