TWO YEARS AGO, KIM INVESTED RMP AT HER ACCOUNT WHICH EARNS r% simple interest . after eighteen months , she noticed that the amount had become rm 10450 and today amount is rm 10600 . FIND THE VALUE OF p and r

Answer 1

p(1+18(r/12)) = 10450
p(1+2r) = 10600

(1 + 3r/2)/(1+2r) = 10450/10600
r = 0.03

now use that in either equation to find p.
