If the simple interest on $3000 for 3 years is $630, then what is the rate? Use the simple interest formula I=PRT How do I write the equation?

OpenStudy (anonymous):

you already have the formula. interest is 630, time is 3 years and principal is 3000

OpenStudy (anonymous):

so 630 = 3000 * 3 * R. now just solve for R

OpenStudy (anonymous):

thats what I was thinking but it looked like to big a number on one side of the = sign.

OpenStudy (anonymous):

630= 9000(r)
