b. $153.36
c. $189.12
d. $170.30
e. none of these

Results are below.

Explanation:

a.

Future Value= $77,000

Number of periods= 1*12 + (2/3)*12= 20 months

Interest rate (i)= 0.045/12= 0.00375

To calculate the monthly deposit required, we need to use the following formula:

FV= {A*[(1+i)^n-1]}/i

A= monthly deposit

Isolating A:

A= (FV*i)/{[(1+i)^n]-1}

A= (77,000*0.00375) / [(1.00375^20) - 1]

Monthly deposit= $3,714.64

b.

Monthly deposit= $2,000

Interest rate= 0.04/12= 0.0033

Number of periods= 12 months

To calculate the monthly withdrawal, we need to use the following formula:

Monthly withdraw= (PV*i) / [1 - (1+i)^(-n)]

Monthly withdraw= (2,000*0.0033) / [1 - (1.0033^-12)]

Monthly withdraw= $170.26
