Answer: x=11 111.11 USD - investments at 6% interest
25000-11 111.11= 13 888.89 USD investments at 15 % interest
Step-by-step explanation:
Paul wants to have 11% from 25000 USD that is 0.11*25000=2750 USD
Let Paul invests x USD at 6% interest (which makes him 0.06*x USD yearly) and the residual amount, i.e.
25000-x at 15% interest. (Which makes 0.15*(25000-x)= 3750-0.15*x ).
So the total return per year:
0.06*x+3750-0.15*x=2750
3750-0.09*x-2750=0
1000-0.09*x=0
x=1000/0.09
x=11 111.11 USD - investments at 6% interest
25000-11 111.11= 13 888.89 USD investments at 15 % interest
