Question 805046: A person made two investments, and the percentage return per year on each was the same. Of the total amount invested, three-tenths of it plus $600 was invested in one venture, and at the end of 1 year the person received a return of $384 from that venture. If the total return after 1 year was $1120, find the total amount invested.

y(.3x+600)=384,

x = 14000, y = 2/25
