Answer:

You will have $29,000 in 30 years, and you need to start with about $2,772.28 to make $14,000 in 9 years

Explanation:

To find the total investment use the equation
A = P(1 + rt)

Where A equals total investment, P is your start investment, r is your rate, and t is time.


A=2,000(1+(0.45 * 30))


A=2,000(1+13.5)


A=2,000*14.5


A=29,000

To find the start investment use the equation
P = A / (1 + rt)


P=14,000/(1+(0.45*9))


P=14,000/(1+4.05)


P=14,000/5.05


P=2,772.28
