A company has Fixed costs: $23500
Variable costs: 2/5x+222 dollars PER UNIT, with x being the total number of units produced.
Selling price: 1275-3/5x dollars PER UNIT.
a) Write the cost function.
b) Write the revenue function.
c) Find the maximum profit and the level of production that will achieve the maximum profit.
(DO NOT use calculus to solve. This is not a calculus course and the derivative is not the answer here.)

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
