You can put this solution on YOUR website!
Let +x+ = amount invested in 1st account
+40000+-+x+ = amount invesed in 2nd account
The 1st account earns +.025x+
for the 1st year
The 2nd account earns +.04%2A%28+40000+-+x+%29+
for the 1st year
Total interest earned is:
+1330+=+.025x+%2B+.04%2A%28+40000+-+x+%29+
Solve for +x+, then find:
+x+ and
+40000+-+x+
