Formula for rate of interest???

OpenStudy (anonymous):

If $700 earns $112 simple interest in 2 years, find the rate of interest. If I could just get the formula for it and description of what each variable in the formula means or represents I could do the rest.

OpenStudy (wolf1728):

Simple Interest Interest = rate * Principal * time periods 112.00 = rate * 700.00 * 2 rate = 112.00/1,400.00 rate = .08 or rate = 8%
