4x + y = 600

and maximize A = xy

amistre64 · Answer

if we let y = 600 - 4x, we can substitute it into area; then it amounts to seeing the A is a quadratic

amistre64 · Answer

either find the vertex, or take a derivative ... your call

O. Wow. That makes sense. Thank you. I was confused on how to represent the y and x in the area formula.
