Answer:

At the end of four years, Melanie will have $2,824.78

Step-by-step explanation:

To calculate the amount Melanie will have at the end of four years with annual compounding interest, we can use the formula for compound interest:

A = P (1 + r/n)^(nt)

Where:

A is the total amount after the specified time

P is the principal investment

r is the annual interest rate (as a decimal)

n is the number of times the interest is compounded per year

t is the number of years

In this case, P = $2500, r = 0.03, n = 1 (since the interest is compounded annually), and t = 4. 

Plugging these values into the formula, we get:

A = 2500 (1 + 0.03/1)^(1*4) A = 2500 (1.03)^4 A = $2,824.78

Therefore, at the end of four years, Melanie will have $2,824.78

SI=(P*R*T)/100

P=2000

R=1.5

T=6

SI=(2000*1.5*6)/100

=(2000*9)/100

=180

Neil will earn interest of 180
