Answer 1

a.We use the formula:
A=P(1+r/100)^n
where
A=future value
P=present value  
r=rate of interest
n=time period.

A=400*(1.12)^5

=400*1.76234168

=$704.94(Approx)

b.We use the formula:
A=P(1+r/2)^2n
where
A=future value
P=present value  
r=rate of interest
n=time period.

A=400*(1+0.12/2)^(2*5)

=400*1.7908477

=$716.34(Approx)

c.We use the formula:
A=P(1+r/4)^4n
where
A=future value
P=present value  
r=rate of interest
n=time period

A=400*(1+0.12/4)^(4*5)

=400*1.80611123

=$722.44(Approx)

d.We use the formula:
A=P(1+r/12)^12n
where
A=future value
P=present value  
r=rate of interest
n=time period.

A=400*(1+0.12/12)^(12*5)

=400*1.8166967

=$726.68(Approx)
