The formula for the perimeter of a rectangle can be written as P= 2(l+w). Solve the formula for the length l.

Ronch [10]

Undo what is done to l. l has w added and the sum multiplied by 2, so divide by 2 and subtract w:

... l = P/2 -w

X: # of pairs of socks; y: # of blouses
Then $2.99x+$12.99y=$43.92.

How to do this and find the max or min points

Veronika [31]

I see your last line is : c(x) = 0.9(x^2-10)^2 + 101.1

Let y = x^2, then c(y) = 0.9(y-10)^2 + 101.1

Apparently, c(y) is a parabola, min is 101.1 when y = 10, max is infinity

So let x^2 = 10 -> x = sqrt(10) or -sqrt(10), min is 101.1, max is infinity
