hey guys,

i have a question in destroyer QR #119. Amanda saves up $18,000 from her job a sa babysitter and puts her money into two different banks, a and b. bank a pays 8% interest and bank b pays 5% interest, each compounded annually. amanda waits one year and discovers she has $19,250 dollars. how much interest did she earn from bank b?

i see the solution manual did one variable and one equation. i was wondering how could this be solved using the system of equations

i know the first part is a+b = $1,250
