I can help, which question do you need help in?
Let
X is the amount invested at 0.12
Y is the amount invested at 0.11
x+y=27727....First equation
0.12x-0.11y=211.32...second equation
multiply both sides of the first equation by 0.11 to get
0.11x+0.11y=3,049.97
0.12x-0.11y=211.32
add these equations together we will get
0.23x=3,261.29
Divide both sides by 0.23 to get
X=14,179.52 this is the amount invested at 0.12
Now the amount invested at 0.11 is
27727-14179.52=13,547.48
Check your answer using the second equation
14,179.52×0.12−13,547.48×0.11
=211.32. Correct
