what formula should I use A=P(1+r/n)^nt
OpenStudy (anonymous):
"....2.4% simple interest " ==> I = P r t

so 1859.69(0.024)(9)
OpenStudy (anonymous):
1859.69(0.216)

thanks. This is all confusing to me. I have examples in my note book but whenI follow them I get something totally different
OpenStudy (anonymous):
I'm glad it works out :)

2.4% is yearly, so what you wanna do is 1859.69 + 1859.69(0.024/12)(9) = 1893.16
