an investor wishes to realize a return of 12 percent on a total of two investments. if he has 10,000 pesos invested at 10 percent, how much additional money should be invested at 16 percent?
Answer provided by our tutors
Let investor invested $x at 16 percent.
So, x*0.16+10000*.1=(x+10000)*(0.12)
0.16x+1000=0.12x+1200
0.04x=200
x=200/0.04=5000
Investor invested 5000 at 16%.
