Respuesta :

Answer

x = amount invested at 11% profit

y = amount invested in stock

x + y = 14.000 (equation)

0.11x - 0.05y = 1.380

x = 14.000 - y

0.11(14.000 - y) - 0.05y = 1.380

1.540 - 0.11y - 0.05y = 1.380

0.16y = 160

y = 10.000

x = 14.000 - 10.000

x = 4.000

amount invested at 11% = $4,000

amount invested in stock = $10,000
