2 A manufacturer finds that the profit EP from assembling r bicycles per day is given by P(x) = -2° +502 - 200.
a How many bicycles should be assembled per day to maximise the profit?
6 Find the maximum profit.
( What is the loss made if no bicycles are assembled in a day? Suggest why this loss would be
made.

24+x=y

step-by-step explanation:

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
