Will someone please help me with this? I tried getting help but it didn’t work

Answer 1

`\begin{gathered} A=\text{ amount invested in fund A} \\ B=\text{ amount invested in fund B} \\ \text{Interest in fund A =}3\text{ \%=0.03} \\ \text{Interest in fund B =}7\text{ \%=0.07} \\ Equation\text{ system} \\ A+B=20300\text{ (1)} \\ 0.03A+0.07B=1109\text{ (2)} \\ \text{From (1) Solving A} \\ A+B=20300 \\ A=20300-B \\ U\sin g\text{ A in (2)} \\ 0.03(20300-B)+0.07B=1109 \\ 609-0.03B+0.07B=1109 \\ -0.03B+0.07B=1109-609 \\ 0.04B=500 \\ B=(500)/(0.04) \\ B=12500 \\ \text{Then} \\ A=20300-12500 \\ A=7800 \\ He\text{ }invested\text{ \$7800 in fund A and \$12500 in fund B} \end{gathered}`
