Question 402708: I'm trying to determine how much E85 fuel to mix with E10 fuel to arrive at a final mixture of E20 in a 16 gallon gas tank. I think the equation would be .85X + .1X = .2, but I'm not sure about how you factor in the 16 gallon tank capacity.

I'm trying to determine how much E85 fuel to mix with E10 fuel to arrive at a
final mixture of E20 in a 16 gallon gas tank.
I think the equation would be .85X + .1X = .2, but I'm not sure about how you
factor in the 16 gallon tank capacity.
:
let x = amt of E85 fuel
then
(16-x) = amt of E10
:
The equation would be
.85x + .10(16-x) = .20(16)
