You'll use the formula I = P*r*t where the interest earned is I = 1330, the amount invested is P = 7000 and the time is t = 2 years. So, I = P*r*t 1330 = 7000*r*2 then you solve for r what do you get @is3535

i think it c

OpenStudy (is3535):

I = Prt This is the formula to find Interest Rate. We are given the Interest Rate, Principal, and time(in years). So we plug in what we know and solve for 'r'.
