Question 571145: Henry invest money in two plans. He invest three-fifths of the money in an account at a return rate of 7%. He invests the remainder of the money in an account with a return rate of 3%. I f the total intrest earned in one year for the investments is $54.00, how much was invested in each plan. i made a chart that says account, rate, principal, and intrest
under account i have first account and second account. under rate i have 0.07 and 0.03. and under principal i have 3/5p but my problem is i dont know how to find 0.03's principal. so for 0.07 in the intrest box i have 0.07*3/5p.
