Hi, today we are solving the question in which y is given as 25x -9000 by 2.
00:09
So we need to firstly found the variable cost per unit.
00:13
So here y is the total manufacturing cost y of making x unit of a toy.
00:20
So variable cost is given by variable cost per unit is given by cost per unit into total number of units.
00:38
So here if we substitute, so cost per unit is y into x.
00:47
Y is 25x -9000 by 2 into x.
00:54
So here we get 25x square minus 9000 x divided by 2 as variable cost.
01:04
So therefore we can conclude that variable cost is given by 25x square minus 9000 into x by 2 per unit.
01:16
Now we need to find secondly the fixed cost.
01:21
So fixed cost is given by, so it is given by total manufacturing cost minus variable cost into units produced.
01:38
So here if we substitute total cost is y minus variable cost is 25x square minus 9000 x divided by 2 into x.
01:55
So here we get it as y is 25x -9000 by 2 minus 25x cube minus 9000 x square by 2.
02:15
Now on solving it 25x -9000 minus 25x cube minus 9000 x square divided by, so fixed cost is given by, therefore required fixed cost is equals to 25x cube minus 25x cube plus 9000 x square plus 25x minus 9000 divided by, so from here this is the fixed cost per unit.
03:15
Now we need to find the average cost of manufacturing...
