Some money at 0.08: Let this amount be x
And 1300 less than that amount at 0.05: this amount will be x-1300
------------------------
0.08x + 0.05(x-1300) = 169
0.08x + 0.05x-65 = 169
0.13x = 234
x = 1800 this is the amount invested at 8%
1800-1300 = 500 and this the amount at 5%
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Check
0.08(1800) + 0.05(500) = 144 + 25 = 169 Correct
