Alabama Instruments Company has set up a production line to manufacture a new calculator. The rate of production of these calculators after t weeks is dx dt = 5000 1 − 100 (t + 10)2 calculators/week. (Notice that production approaches 5000 per week as time goes on, but the initial production is lower because of the workers' unfamiliarity with the new techniques.)

Alice and Bob have two positive integers, x and y respectively, glued to their foreheads, so that each can read the other’s number but not their own. They also know that |x − y| = 1. The following conversation is overheard between Alice and Bob:Alice: I don’t know my number.Bob: I don’t know my number.Alice: I don’t know my number.Bob: I don’t know my number.They say this to each other 200 times. And then we overhear them say: Alice: I know my number! Bob: I know my number too!Can you explain the conversation and figure out the numbers x and y. You may assume that Alice and Bob each know that the other is extremely smart — so each is confident that if the other has sufficient information to deduce the answer then he/she definitely will.
