You mean TWO kinds instead of TWELVE kinds.

VARIABLES:
j, how much Jamaican Coffee
v, how much Vanilla Bean Coffee

Continuing to try, the mixture is j+v.
, the mixture, IS, ten pounds more, than two times the amount of Jamaican coffee.
Simplify that is some useful way.

-----we can work with this.

Back to the fundamental two part mixture problem,

Substitute according to the complicated description part, for j.

A unsimplified linear equation in just the one variable, v.
...
and you know what to do from that.....?
