Answer:

(a) 3 years FV=$4,221.80

(b) 6 years FV=$5,092.46

(c) 9 years FV=$6,142.69

Step-by-step explanation:

The formula for continuously compounded interest is

FV = PV x e^(i x t)

where,

FV=future value of the investment,

PV= present value,

i = stated interest rate,

t = time in years,

e= mathematical constant approximated as 2.7183.

In this case,  

PV=$3,500

i = 6.25%

(a) 3 years

FV = PV x e^(i x t)

FV = $3,500 x e^(6.25%x3)

FV=$4,221.80

(b) 6 years

FV = $3,500 x e^(6.25%x6)

FV=$5,092.46

(c) 9 years

FV = $3,500 x e^(6.25%x9)

FV=$6,142.69
