Okay, here we have a profit function, right, and for the part a, we need to find the value of q that will give the maximum profit.
00:10
Right, so as we can see here, the coefficient of q square, that is negative, right? which means the parabola opens in a downward direction like this, right? and here, vortex, that is the our maximum point.
00:28
Right so here we need to just find the x coordinate of the vertex or we can say here q coordinate of the vertex right so the q coordinate of the vortex is given by the equation minus b upon 2a now what is b so b that is the coefficient of q and a that is the coefficient of q square right now substituted the values of a and b in this equation so so here q that is approximately equal to 83 .333.
01:12
Right, so this is going to be your answer number a.
01:22
Now we need to find the maximum profit, right? so for that, we need to substitute the value of q in this profit function.
01:31
So here, p is equal to minus 0 .03, multiply by q square, but here q is equal to 83 .333 plus 5 ,000, and here again q is equal to 83 .3333 .3...
