Answer 1

We use the formula:  
A=P(1+r/365)^365n
where   
A=future value
P=present value  
r=rate of interest
n=time period.

a.A=4200*(1+0.058/365)^(365*6)

=4200*1.4161931

=$5948.01(Approx)

b.A=4200*(1+0.058/365)^(365*11)

=4200*1.89259578

=$7948.90(Approx)

c.A=4200*(1+0.058/365)^(365*18)

=4200*2.84032096

=$11929.35(Aprox)
