<h2>The Third table of ordered pairs represents a proportional relationship. </h2>

Explanation:

A proportional relationship is defined as the relationship between two quantities where one is directly proportional to another with a proportionality constant.  

For example, y = ax

Here a is the proportionality constant.  

This expression shows that y varies directly as x varies.  

From the tables mentioned in the below attachment, we can easily say that "Table 3" has the ordered pairs which represents proportional relationship.

Table 3 defines y is directly proportional to x with proportionality constant \frac{1}{7}.

Using the functions presented in the example, how much can Cam expect to earn if he sells all the corn produced on 1.5 acres?
12345 [234]

Answer:

Cam expect to earn if he sells all the corn produced on 1.5 acres is $8725.

Step-by-step explanation:

Given : C(a)=7500a-1500, M(C)=0.9C- 50  and  M(C(a))=6750a-1400

To find : How much can Cam expect to earn if he sells all the corn produced on 1.5 acres?

Solution :  

C(a)=7500a-1500

Substitute a=1.5,

C(1.5)=7500(1.5)-1500

C(1.5)=11250-1500

C(1.5)=9750

Now, taking function M(C)=0.9C- 50

Substitute C=9750,

M(9750)=0.9(9750)- 50

M(9750)=8775- 50

M(9750)=8725

Now, taking function M(C(a))=6750a-1400

Substitute a=1.5,

M(C(1.5))=6750(1.5)-1400

M(C(1.5))=10125-1400

M(C(1.5))=8725

Therefore, Cam expect to earn if he sells all the corn produced on 1.5 acres is $8725.
