Simple Interest = PRT/100

P = $3000

R=4.5

T=5

substitute into the formula


\text{Simple Interest =}(3000*4.5*5)/(100)
=675

Simple interest = $675

Compound interest


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

P=3000

r = 0.045

n=1

t=5


A=3000(1+(0.045)/(1))^(1*5)
=3000(1.045)^5
=3738.55

A = P + I

3738.55 = 3000 + I

I = 738.5458

compound interest= $738.5458

But we were asked to find the difference between simple interest and compound interest

$735.5458 - $675 = $60.5458 ≈ $60.55
