XYZ = MICROSOFT It is no conspiracy

anonymous · Answer

There must be some expression in the question..

anonymous · Answer

Yes!  There is, I forgot!  Sorry!

N(x) = 100+20*ln(0.25x)

anonymous · Answer

I plugged in the 100,000 and multiplied it by .25, but not sure how to go from there!

anonymous · Answer

N(x) stands for computrs sold, am I right?

anonymous · Answer

yes?  That's what I am assuming!

anonymous · Answer

well i'm assuming you can use your calculator for this one unless you are a super computer

anonymous · Answer

damn you polar coordinates I WANT RECTANGULAR

anonymous · Answer

yes, but I get lost in the steps...
from here I get
100+ 20* ln(25,000)
after that I get 302.53, but I'm pretty sure the number should be much higher!

anonymous · Answer

Yes..   you are right

anonymous · Answer

I thought the number would be larger - THANKS!

anonymous · Answer

yeah 302.53 is what i'm getting also

anonymous · Answer

I lawled when my calculator can't process 100000 on the graph

dumbcow · Answer

jenn
think of it this way, if they sell each computer for 1,000 dollars then thats like making 302,000 from spending 100,000 on advertising
so its still a profit and 302 makes more sense
