Compute the price of $50,118,144 received for the bonds by using Table 1, Table 2, Table 3 and Table 4. Round to the nearest dollar. Your total may vary slightly from the price given due to rounding differences.

Present value of the face amount	$
Present value of the semiannual interest payments
Price received for the bonds	$50,118,144

I am not understanding how to figure out the present value or the semiannual interest payment value at all.
