The sum of the first number and twice the second number is 108 and the product is a maximum.
So I did
x + 2x = 108
x+x=108/2 = 54
x=54/2 = 27
54,27 Im not sure if this is the right way to do it?
you can solve this using calculus ... ... and determine the value of that maximizes
or, without calculus ... you can remember something about the graph of a quadratic function w/ a negative leading coefficient and where the maximum is located.
