\left \{ {{T+S=925} \atop {4T+6S=4524}} \right.  \\ S=925-T \\ 4T+6(925-T)=4524 \\ 4T+5550-6T=4524 \\ -2T+5550=4524 \\ -2T=-1026 \\ T=513
So they sold 513 turkey sandwiches

Farmer has 2,400 feet of fencing and wants to fence off a rectangular field that borders a straight river. he needs no fence alo
konstantin123 [22]

<span>Let each side perpendicular to the river be "x".
Then the side parallel to the river is "2400-2x".</span>

 

The function would be:

<span>A(x) = x(2400-2x)

</span>

And it would be: A(x) = 2400x - 2x^2

 

To solve the equation:

<span>
You have a quadratic with a = -2 and b = 2400

</span>

Maximum Area happens where:

x = -b/2a

= -2400/(2*-2)

<span>= 600 ft. (width)

</span>

To find the length it will be:

 

<span>= 2400-2x = 2400-2*600 = 1200 (length)</span>
