Question 397651
Let A be the amount invested at 3%, B the amount at 4%.
Total value:
1.{{{A+B=8000}}}
Interest:
{{{0.03A+0.04B=295}}}
2.{{{3A+4B=29500}}}
Multiply eq. 1 by -3 and add to eq. 2,
{{{-3A-3B+3A+4B=-24000+29500}}}
{{{highlight(B=5500)}}}
Then from eq. 1,
{{{A+5500=8000}}}
{{{highlight(A=2500)}}}
