Question 437844
<font face="Times New Roman" size="+2">


Let *[tex \Large x] represent the number of grams of cashews.  That quantity of cashews mixed with 500 grams of peanuts makes *[tex \Large 500\ +\ x] grams of mixture, 20% of which must be *[tex \Large x] grams of cashews.  Hence:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 0.2(500\ +\ x)\ =\ x]


Just solve for *[tex \Large x].

*[tex \LARGE e^{i\pi} + 1 = 0]
My calculator said it, I believe it, that settles it
