Question 908255
We know that the interest for the two accounts is $68
0.06*x+0.05*y=68
We know that the account at 6% has 2 times the amount at 5%
We substitute for x
0.06*(2*y)+0.05*y=68
We multiply out
(0.12+0.05)*y=68
We combine like terms.
0.17*y=68
Isolate y
y=  400.00
y=$  400.00 at 5%
Calculate x
x=2*y
x=$  800.00 at 6%
Your total for x  is $  800.00
Your total for y is $  400.00
Your total for x and y is $ 1200.00
Total invested $  800.00 + $  400.00=$ 1200.00
We check
0.06*  800.00+0.05*  400.00=68
   48.00+   20.00=68
68=68
Since this statement is TRUE and neither is negative then all is well.
