$[$Related to Solved Problem $3\mathrm{.}3]$ For each of the following situations, choose the equation needed to calculate the yield to maturity. You do not have to solve the

equations for $i$; just choose the appropriate equations.

A simple loan for $$330,000$ that requires a payment of $$540,000$ in three years.

A$.330,000=540,000(1-i{)}^3$

B$.330,000=\frac{540,000}{(1+i{)}^3}$

C$.330,000=\frac{540,000}{i}$

D$.330,000=540,000i$

A discount bond with a price of $$1,000$ that has a face value of $$1,000$ and matures in four years.

A$.1,000=\frac{1,000}{(1+i{)}^4}$

B$.1,000=1,000(1-i{)}^4$

C$.1,000=1,000(1-i)$

D$.1,000=\frac{1,000}{(1+i)}$
