1. The problem statement, all variables and given/known data Pat invested a total of 3000$. Part of the money was invested in a money market account that paid 10 percent simple annual interest, and the remainder of the money was invested in a fund that paid 8 percent simple annual interest. If the interest earned at the end of first year from these investments was 256$, how much did Pat invest at 10 percent and how much at 8 percent? 2. Relevant equations V = P(1 + rt/100) V= interest amount P = Principal amount r = rate t = time in years 3. The attempt at a solution P = TenP + EightP or 3000 = TenP + EightP V= TenV + EightV or 256 = TenV + EightV For 10% TenV = TenP ( 1 + 0.1 *1) For 8% EightV = EightP(1 + 0.08 *1) I have not developed the full solution but is it fine to work in this way or there is any other possibility? Some body please guide me. Zulfi.
