Question 970109
Amount in Account 1 is x
Amount in Account 2 is $10,000-x;  Their sum is $10,000

Account 1 pays .08x per year   I=PRT

Account 2 pays (.1)(10.000-x) per year

Their sum is $940

.08x + 1000-.10x=940   We distribute the .1 over the (10,000-x)

Collect terms and subtract 1000 from both sides
-0.02x=-$60
Divide by (-1)
0.02 x=60
Multiply by 50 (or divide by 0.02)
x=3000  @ 8%,  $240/year  ACCOUNT 1
10,000-x =$7000 @ 10%, $740 year  ACCOUNT 2

Their sum is $940.
