Question

An investor invested a total of $2500 in two mutual funds. One fund earned a profit of 4% and the other earned a 2% profit. If the investor's total profit was $70 how much was invested in to each fund?

Answer 1

x,y= Investments in each of the firms
x+y=2500 (i)
also, given 4% of x + 2% of y =70
--> 0.04x + 0.02y=70 (ii)
Multiplying (i) by 0.02
0.02x + 0.02y= 50 (iii)
Subtracting (iii) from (ii), 0.02x=20 -->x=1000 so y=1500
Answer: $1000 invested in 4% profit fund and $1500 invested in 2% profit fund

Answer 2

Thank you that makes total sense now that I see it
