Question 330354
<font face="Garamond" size="+2">


Let *[tex \Large x] represent the number of units of lumber produced.  Then let *[tex \Large y] represent the number of units of plywood produced.  We are given that *[tex \Large y\ =\ 3x].


The profit equation is:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 30x\ +\ 50y\ =\ 18540]


Substituting what we know about the relationship between *[tex \Large x] and *[tex \Large y],


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 30x\ +\ 50(3x)\ =\ 18540]


Just solve for *[tex \Large x] and then multiply that by 3 to get *[tex \Large y]

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