x is the amount carla invests at 14%
28,000-x would then be the amount invested at 9%
x(0.14) + 28000-x(0.09) = 3370
0.14x + 2520 - 0.09x = 0.05x + 2520 = 3370
x = (3370-2520)/0.05 = 17000
the answer is (a)

There are only 4 possible answers - try them all out and see which is right?
9% of 28000 is 3,920 so start from the highest and figure it out.
18000*0.14 + (28000-18000)*0.09 = ?
