emission of greenhouse gases

Greenhouse gases are naturally present in the atmosphere in order to keep the earth warmer by trapping some of the sun's rays on earth. Greenhouse gases include water vapor, carbon dioxide, methane, nitrous oxide, ozone, chlorofluorocarbons, and hydrofluorocarbons. 

Human activities contribute to the emission of greenhouse gases in the atmosphere through fossil fuel use, industrial processes, and intensive livestock farming, among others. Emission of large amounts of greenhouse gases can increase their natural levels in the atmosphere, possibly resulting to global warming.

What is the size of the payments that must be deposited at the beginning of each 6-month period in an account that pays 8.6%, co
Burka [1]

Answer:

The answer is $86,167.57 (to 2 decimal places)

Explanation:

In this question, we are to calculate the present value of a certain amount that is compounded semiannually, and after 10 years, yields a future value of $200,000. To calculate this, we will use the formula for calculating present value as follows:

PV = FV ÷ (1+\frac{r}{n})^{n*t}

where:

PV = present value = ???

FV = future value = $200,000

r = interest rate in decimal = 8.6% = 0.086

n = compounding period pr year = semiannually = 2

t = time of compounding in years = 10

Therefore,

PV = 200,000 ÷ (1+\frac{0.086}{2})^{2*10}

PV = 200,000 ÷ (1.043)^{20} = $86,167.57
