Present calculations to show the following:

(a) the present value of \(\$ 30,000\) to be received nine years hence, discounted at \(16 \% ;(b)\) the total present value of three payments consisting of \(\$ 35,000\) to be received one year hence, \(\$ 45,000\) to be received two years hence, and \(\$ 60,000\) to be received three years hence, all discounted at \(14 \%\);

(c) the present value of five payments of \(\$ 9,000\) each, with a payment to be received at the end of each of the next seven years, discounted at \(12 \%\).
