Question 358365
<font face="Garamond" size="+2">


Yep,


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ M\ =\ 150\ +\ 0.38x]


is the linear relationship where *[tex \Large M] represents the money raised, and *[tex \Large x] is the amount of income from subscriptions.


If you want *[tex \Large M\ =\ 300], then solve


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 150\ +\ 0.38x\ =\ 300]


for *[tex \Large x]


You might want to round your answer to the nearest "dollar."  I don't know what a "dollor" is.

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