A farmer finds that if she plants 70 trees per acre, each tree will yield 30 bushels of fruit. She estimates that for each addit
Serjik [45]

The farmer should plant 40 trees per acre to maximize her yield to harvest.

<h3>What is a system of equations?</h3>

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

Let F be the number of fruit per acre  

F = (70 + x) \times  (30 - 3x)  \\F = 70  \times 30 - 70 \times 3x + 30  \times x - 3x^2  \\F = 2100 - 210 x + 30x - 3x^2  \\F = 2100 - 180x - 3x^2

Factor out the 3 and complete the square

F = -3x^2 - 180x + 2100\\F = -3 \times  (x^2 + 60x - 700)  \\F = -3 \times (x^2 + 2 * 30x + 30^2 - 30^2 - 700)  \\F = -3 \times ((x + 30)^2 - 500 - 900)  \\F = -3 \times  ((x + 30)^2 - 400)  \\F = -3 \times  (x + 30)^2 + 1200\\

So the vertex is at (-30, 1200)  

70 - 30 = 40  

The farmer should plant 40 trees per acre to maximize her yield to harvest.
