Hi, could someone explain me or pin me the solution of this Data sufficiency question ? I struggle to understand the solution the daily profit, P, for selling x units of a certain item at a sporting goods store can be moddeled by the function P(x) = -a(x- b/2a)^2 + (b)^2 /4a + c, where a and b are positive constant and c nonnegative constant. what is the maximum daily profit for selling this item? 1) b^2 + 4ac = 52ac/3 2) c = 360

Can you please share the source of the question? Also, the screenshot would be nice. Thank you!

The question is discussed here the-daily-profit-p-for-selling-x-units-of-a-certain-item-at-427551.html It’s from one of the gmat official mocks

Idk if this is still a doubt or not but based on what i understand if you sort the table by time and if the difference between 2 "time of update"s is less than 3 mins then the length of download is always more than 3 mins for those people. Think of it as if u get the most of your wifi speed when you alone are on the network however if everyone around you is using the wifi too then the speed drops and your download slows down. I apologize for the analogy in advance xD
