Best ResponseYou've already chosen the best response.0Let funds deposited into account 1 be A and funds deposited into account 2 be B. A + B = 4000, since the total amount invested is $4,000. Since A earns interest at 3% and B earns interest at 5%, we can set up a second equation like this: A*.03 + B*.05 = 180

Best ResponseYou've already chosen the best response.0So you have A+B=4000 And .03A + .05B=180 Can you solve one of those for A or B? The first one, maybe?

Best ResponseYou've already chosen the best response.0Let's solve for A by subtracting B from both sides: A+B=4000  B  A =4000B

Best ResponseYou've already chosen the best response.0Now you can substitute that in for A in the second equation: .03(4000B) + .05B = 180

Best ResponseYou've already chosen the best response.0Well, .03*4000 = 120.00. But that is not the answer to the problem. We need to solve for A and B.

Best ResponseYou've already chosen the best response.0.03*4000 .03B+.05B = 120 + .02B = 180 Subtract 120 from both sides .02B=60 Divide 60/.02=B=3000 Plug back in to the original equation A+3000=4000 Therefore A = 1000 and B = 3000

Best ResponseYou've already chosen the best response.0I already answered the question. .03*4000 .03B+.05B = 120 + .02B = 180 Subtract 120 from both sides .02B=60 Divide 60/.02=B=3000 Plug back in to the original equation A+3000=4000 Therefore A = 1000 and B = 3000
