Problema Solution
Susan Marciano invested part of her $22,000 bonus in a fund that paid a 10% profit and invested the rest in stock that suffered a 5% loss. Find the amount of each investment if her overall net profit was $400.
Answer provided by our tutors
let
x = the money invested in a fund that paid a 10% profit
y = the money invested in a stick that suffered a 5% loss
x + y = 22000
0.10x - 0.05y = 400
by solving the above system of equations we find:
x = $10,000
y = $12,000
