Question 349991
<font face="Garamond" size="+2">


150 times 200 is 30000, so clearly more than 150 were ordered.  Hence the price of each box is *[tex \Large 200\ -\ x] and the number of boxes ordered is *[tex \Large 150\ +\ x], so:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ (200\ -\ x)(150\ +\ x)\ =\ 30625]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ x^2\ -\ 50x\ +\ 625\ =\ 0]


Solve for *[tex \Large x].  Add to 150.

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