The profit P for a company is P = 100xe−x/400, where x is sales. Approximate, using differentials, the change and percent change in profit as sales increase from x = 115 to x = 120 units. (Round your answers to two decimal places.)
I think I have it. I am going to check with my sister who teaches math really fast. :P
Wait...what is e? I didnt see that.
I don't have e. I was just given P=100xe^-x/400
are you solving for e?
I'm trying to find the percentage change.
