Best ResponseYou've already chosen the best response.0You are trying to maximize the product yz. so let z= the product = to xy

Best ResponseYou've already chosen the best response.0okay, so solve x+2y=100 for x. x=1002y z=xy z=(1002y)y z=y(1002y) z=100y2y^2

Best ResponseYou've already chosen the best response.0Let me simplify this down a bit, because I was writing out my work which may be a bit confusing.

Best ResponseYou've already chosen the best response.0So, you have been told that the sum of the first number, twice the second is 100 (I'll use just x and y this time to make things less confusing) so, x+2y=100.

Best ResponseYou've already chosen the best response.0You are trying to minimize the product, P=xy. So solve the first equation x+2y=100, for x.........x=1002y. Now substitute this into the product formula ( P=xy)

Best ResponseYou've already chosen the best response.0P = xy = (100 − 2y)y = 100y − 2y^2
