Using the problem, create an equation to find the number (x).
Three less than (so x minus 3) 6 times a number (6 times x) equals 39.
6x-3=39, solve for x.
x = 7

Answer:
52 Trees
Step-by-step explanation:
If she plants 85 trees per acre, each tree will yield 80 bushels of fruit.
Yield = 85 X 80
Let x be the additional tree planted per acre.
For each additional tree planted per acre, the yield of each tree will decrease by 4 bushels.
Therefore, the yield:

Next, we maximize F(x) by taking its derivatives and solving for its critical point.


It is apparent that she currently has too many trees per acre. To get a maximum harvest, she needs to reduce the number of trees by approximately 32.5 trees.
Therefore, number of trees per acre she should plant:
85+(-32.5)
=85-32.5
=52.5 Trees
Since the number of trees can only be an integer and it cannot be greater than 52.5, the number of trees to be planted per acre to maximize her harvest is 52.
<em><u>The reciprocal property is:</u></em>

<em><u>Solution:</u></em>
Given that,

<em><u>The reciprocal property is given as:</u></em>
The reciprocal of a fraction is the numerator and denominator switched

Therefore,

By reciprocal property,
Switch the numerator and denominator of right side fraction as well as left side fraction
The we get,

Thus option C is correct
