=======================================
A dairy farmer wants to mix a H% protein supplement and a standard L% protein ration to make M pounds of a high-grade T % protein ration. How many pounds of each?
=======================================

v pounds of H% protein supplement
M-v pounds of L%

Hv%2BL%28M-v%29=TM
-
Hv%2BLM-Lv=TM
Hv-Lv=TM-LM
v%28H-L%29=M%28T-L%29
highlight%28v=M%28%28T-L%29%2F%28H-L%29%29%29
Substitute your given values. Evaluate v. Use this to evaluate M-v.
