Lance rice has decided to invest $1,200 quarterly for eight years in an ordinary annuity at 4%. the total cash value of the annuity at end of year 8 is (use the tables in the handbook):

First step is to compute for the interest that is gained from the described investment.
                             I = P x i  x n
where P is the principal amount, i is the interest rate, and n is the number of years.
                             I  = ($1200) x 0.04 x 8 = $384
Then, we add the interest gained to the original amount. 
                        F = P + I = ($1200) + ($384) = $1584
Thus, the amount after 8 years is $1584. 

Good it’s definitely option a

The business cycle is the periodic but irregular up-and-down movement in economic activity, measured by fluctuations in real gross domestic product (gdp) and other macroeconomic variables. a business cycle is typically characterized by four phases—recession, recovery, growth, and decline—that repeat themselves over time. economists note, however, that complete business cycles vary in length. the duration of business cycles can be anywhere from about two to twelve years, with most cycles averaging six years in length. some business analysts use the business cycle model and terminology to study and explain fluctuations in business inventory and other individual elements of corporate operations. but the term "business cycle" is still primarily associated with larger (industry-wide, regional, national, or even international) business trends.
