Question 330598
<font face="Garamond" size="+2">


Let *[tex \Large x] represent the cost of a fake fur coat and *[tex \Large y] represent the cost of a leather coat.  Then *[tex \Large 25x] is the cost of 25 fake fur coats and *[tex \Large 15y] is the cost of the *[tex \Large 40\ -\ 25] leather coats, so:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 25x\ +\ 15y\ =\ 9300]


Similarly,


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 10x\ +\ 30y\ =\ 12600]


Solve the system for *[tex \Large x] and *[tex \Large y], and then substitute the values into:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 20x\ +\ 20y]


To calculate the cost of an evenly split order.

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