We know that Interest= PNR/ 100. where P is the principal R is the rate of Interest N is the no of years the sum has been invested for. Since N is not given we assume that to be 1 Therefore we have 10x /100 + (7000 -x)*7/100= 580
Multiplying both sides by 100 10x+(7000-x)*7 = 58000 simplifying 10x+ 49000 - 7x = 58000 3x = 58000-49000 3x = 9000 x= 3000 therefore the sum of money invested at 7% = 7000 - 3000 = 4000

Using the given conditions, we establish two equations. The first from the total invested amount which of 7000 dollars and the second from the total interest of $580. We solve the system of equations to find the value of x, which signifies the amount invested at 10%. The rest of the money (7000 - x) was invested at 7%. ;

Walt invested $4000 at a 7% interest rate. This was determined by setting up equations based on the amount invested and the total interest earned. After calculating, it was found that $3000 was invested at 10%, leaving $4000 for the 7% investment.

[tex]12.5 \times 8 \\ = \frac{125}{10} \times \frac{8}{1} \\ \\ = \frac{125 \times 8}{10 \times 1} = \frac{1.000}{10} = 100[/tex]
