Question 1027767
<font face="Times New Roman" size="+2">


The cost per person for *[tex \Large x] people going on the trip is:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ C(x)\ =\ \frac{4400}{x}]


If two less people attend:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ C(x-2)\ =\ \frac{4400}{x\ -\ 2}]


But *[tex \Large C(x)\ =\ C(x\ -\ 2)\ -\ 110],


So:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ \frac{4400}{x}\ =\ \frac{4400}{x\ -\ 2}\ -\ 110]


Solve for *[tex \Large x], then calculate *[tex \Large x\ -\ 2]

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

*[tex \Large \ \
*[tex \LARGE \ \ \ \ \ \ \ \ \ \
