I know that T = 8 years, I think the P = 1800, and the R = 5%. Please help Please!

Well I got a 100% and found out it's $4500. Here you go!

This time I did the opposite

I did P divided by R divided by T

1800 divided by 0.5 divided by 8 is $1800

love_ranaa · Answer

I meant 1800 divided by 0.5 divided by 8 is 4500
So that is your investment :)
