an investor invested a total of 2,900 in two mutual funds and one fund earned a 9% profit while the other earned a 7% profit,if the investor total profit was 233. how much was invested in each mutual profit?
I took 9 divides by 2900 = 322.2 is this right?
then i divided 7 by 233= 33.3 is this right

Best ResponseYou've already chosen the best response.0so this means x+y = 2900 is your first equation

Best ResponseYou've already chosen the best response.0since x dollars invested gives you a 9% profit, this means we go from x dollars to 1.09x dollars y dollars invested gives you a 7% profit, this means we go from y dollars to 1.07y dollars they add up to 1.09x + 1.07y

Best ResponseYou've already chosen the best response.0it's given that the "total profit was 233", so 1.09x + 1.07y = 233 Now plug in y = 2900  x to get 1.09x + 1.07y = 233 1.09x + 1.07(2900  x) = 233 and solve for x

Best ResponseYou've already chosen the best response.0oh wait...hmm i'm thinking of something else, the second equation should be 0.09x + 0.07y = 233 plug in y = 2900  x to get 0.09x + 0.07(2900  x) = 233

Best ResponseYou've already chosen the best response.0now solve 0.09x + 0.07(2900  x) = 233 for x

Best ResponseYou've already chosen the best response.0u add 0.09 + 0.07 = 0.16 then u x 2900 =464 so 233x = 464?

Best ResponseYou've already chosen the best response.0i have to get the profit for 9% and also 7 % so I dont think I got it right?

Best ResponseYou've already chosen the best response.00.09x + 0.07(2900  x) = 233 0.09x + 0.07(2900)  0.07x = 233 0.09x + 203  0.07x = 233 0.02x + 203 = 233 0.02x = 233  203 0.02x = 30 x = 30/0.02 x = 1500 So $1500 was invested and it generated a 9% profit
