Find the derivative $A'(x)$: $$A'(x) = 2400 - 4x$$
Optimization problems follow a predictable pattern. If you try to wing it, you’ll get lost in the variables. Instead, follow this checklist: 5.6 solving optimization problems homework
Set $A'(x) = 0$ to find critical numbers: $$0 = 2400 - 4x$$ $$4x = 2400$$ $$x = 600$$ Find the derivative $A'(x)$: $$A'(x) = 2400 -
If the problem mentions a box, a fence, or a ladder, draw it. Label your variables ( or a ladder
Optimization often results in "ugly" numbers like 200the square root of 200 end-root
