<span>The total equivalent warming impact (TEWI) takes into consideration both the direct and indirect global warming effects of refrigerants.
In addition to the direct impact of the refrigerant (which is conveniently estimated by GWP), any system or process, which requires energy input, indirectly affects the environment. This impact is originated from CO2 emissions from the energy production processes.
TEWI can be calculated using the equation below:
TEWI = direct emissions + indirect emissions = (GWP×L×N)+(Ea×β×n),
where
L – annual leakage rate in the system, kg (3% of refrigerant charge annually),
N – life of the system, years (15 years),
n – system running time, years (based on weather data, 4910 hours),
Ea – energy consumption, kWh per year (modelled for each refrigerant),
β – carbon dioxide emission factor, CO2-eq. emissions per kWh (165 g CO2/kWh).</span>
<span>To calculate the number of people for whom to provide supplies for (B) you need to subtract the number of people who brought their supplies (P) from the overall number of people (72).
B=72-P</span>
A company made a profit of $25,000 over a period of 5 years on an initial investment of $10,000. What is its annualized ROI?
Answer: Out of all the options shown above the one that best represents the annualized ROI is answer choice C) 30%. To solve this you first need to determine the data that will be needed to solve it. In this case the initial investment which is 10,000, the total profit: 25,000, and finally the total number of years: 5. Then we simply use the following formula: Return on Investment = (Gain from Investment - Cost of Investment)/ cost of investment. You then multiply the result by 100% and finally divide by the number of years which in this case is 5.
I hope it helps, Regards.
Answer:
Price elasticity of demand = 10.21
Explanation:
Given:
Old income (P0) = $31,900
New income (P1) = $33,500
Old Quantity (Q0) = 3 times
New Quantity (Q1) = 5 times
Computation of Price elasticity of demand :
Midpoint method:
Price elasticity of demand =
Price elasticity of demand = 10.21
