If x dollars is invested at 9 percent for one year and y dollars is invested at 8 percent for one year, the annual income from the 9 percent investment will exceed the annual income from the 8 percent investment by $48. If $2,000 is the total amount invested, how much is invested at 8 percent? Choose the correct choice from the following options:
A) a. $280
B) b. $776.47
C) c. $892
D) d. $1108
E) e. $1200
2 equations with 2 unknowns   9x / 100 - 8y / 100 = 48   and   x + y = 2000   Solving these 2 equations, x = 1223.53 and y = 776.47   Answer b. $776.47.
