Question 1126322
the total is 21,000
part of it at 9%, let it be x
the rest at 14% will be 21,000-x
---------------------------------------
0.09x + 0.14(21,000-x) = 2,790
0.09x + 2,940 - 0.14x
-0.05x = -150 divide -150/-0.05 and remember -/- = +
x = 3,000
The broker has $3,000 invested at 9% and 21,000-3000 = 18,000 at 14%
