how do you solve if jim has $213 interest return and has $3000 invested some at 5% and the Rest at 8% find the amount of invested in each
--------------------------
Quantity: F + E = 3000 dollars
Interest:0.05F+0.08E = 213 dollars
-------
Modify:
5F + 5E = 5*3000
5F + 8E = 213*100
-----------------------
3E = 6300
E = $2100 (amt. invested at 8%)
---------
Solve for "F:
F + E = 3000
E = $900 (amt. invested at 5%)
