Question

Susan Marciano invested part of her $19000 bonus in a fund that paid a 12% profit and invested the rest in stock that suffered a %4 loss. Find the amount of each investment if her overall net profit was $520

Answer 1

Answer: $18,000 was invested at 11% profit

$15,000 was invested at 3% loss

Step-by-step explanation:

11x - .03 x (33000-x)=1530

11 x 18000- .03 x (33000 - 18000) =1530

1980-.03 x 15000 = 1530

1980 - 450 = 1530

1530 = 1530
