You invested $12000 part of it in stock that paid 14% annual interest. however, the rest of the money suffered a 6% loss. if the total annual income from both investments was $680, how much was invested at each rate?

Total investment = 12,000

Let x be invested in Stock at a return of 14%

The rest (12,000-x) invested at a loss of 6%

0.14*x - 0.06*(12,000-x) = 680

0.14x -720 +0.06x = 680

0.2x = 1400

x = 7000

So $7,000 was invested at a rate of 6% and  $5,000 (12000-7000) was invested at a loss of 6%

correct answer is b. 27/8
