Problema Solution
Susan Marciano invested part of her $30,000 bonus in a fund that paid 11% profit and invested the rest in stock that suffered a 4% loss. Find the amount of each investment if her overall net profit was $750
Answer provided by our tutors
Let Susan invested $x of 30.000 in a fund and the rest (30,000 - x) in stock.
profit of the first investment - loss of the second investment = overall net profit
0.11*x - 0.04*(30000 - x) = 750
x = $13,000
Susan invested $13,000 in a fund and the rest 30,000 - 13,000 = $7,000 in a stock.
