It is 5000*(1.06)4*11/2 = 5000*1.0622 = 5000*3.064 approx = 18017.69 You realise, of course, that 6 percent quarterly is equivalent to over 26% per year!
Your going to fail the test.
Principal amount 5,000 Interest rate 9 percent per year = 0.09 Continuous compounding Number of years 7 Future value = P e^rt Future value = (5000) e^(0.09)(7) Amount after 7 years = $9,388.05
The formula to calculate the present amount including compound interest is A = P(1 + r/n)nt where P is the principal amount, r is the annual rate expressed as a decimal , t is the number of years, and n is number of times per year that interest is compounded. In the question, P = 5000, r = 0.07, t = 4, and n = 1 A = 5000(1 + 0.07)4 = 5000 x 1.074 = 5000 x 1.310796 = 6553.98
