a.

\

Find the formula for the interest rate $\"\"$ required to achieve a balance of $\"\"$ in the account after $\"\"$ years is

\

Balance in the account after $\"\"$ years is $\"\"$ .

\

Consider the function as $\"\"$ .

\

Solve for $\"\"$ .

\

$\"\"$

\

Thus, the formula for the interest rate $\"\"$ required to achieve a balance of $\"\"$ in the account after $\"\"$ years is

\

$\"\"$ .

\

$\"\"$

\

b.

\

Find the interest rate $\"\"$ will yield a balance of $\"\"$ after $\"\"$ years.

\

Consider $\"\"$ .

\

Substitute $\"\"$ in the above formula.

\

$\"\"$

\

Thus, the interest rate $\"\"$ will yield a balance of $\"\"$ after $\"\"$ years is $\"\"$ .
