Let's say I have substance A with a closed cup flashpoint of 200° and substance B with a closed cup flashpoint of 110°. If my mixture is a 1 to 2 ratio of A to B, can the mixture's flashpoint be calculated as:
(1x200°)+(2x110°)/3=140°
edit: I should mention that the substances are non-reactive plant based oils.
Can flashpoint be calculated from flashpoint of components?

Good question but the answer is possibly the following. When you mix relatively similar amounts (such as 1:2) of two different flammable materials, flashpoint possibly will be controlled by the most flammable material so it will be close to 110°C
Remember safety first! Check MSDS and consult with professionals before performing risky experiments.
After I wrote my answer I found this useful study. I'm sure you can figure out

Don't be so sure! I'm not very educated in the ways of chemistry and its supporting math.I'm sure you can figure out
You said "... the answer is possibly the following." Perhaps if I give a specific example, you'd be able to be more certain. One example would be soy bean oil with a flash point of 280°C and orange essential oil with a flash point of 57°C.
I really appreciate your help.
