Sagot :

[tex]Interest=Principal*Rate*Time \\ 450= 3000*Rate*1 \\ \frac{450}{3000} =Rate \\ 0.15=Rate[/tex]

Therefore the rate is 0.15*100=15%

To get the percentage, divide the interest by the amount, simply:

P 450 divided by P 3000 is 0.15

changing to percentage, decimal multiplied by 100, simply:

0.15 x 100 =15%

Hope this helps =)
