The graph that shows the proportional relationship y = 0.7x is Graph A.
<h3>What is a proportional relationship?</h3>
A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:
y = kx
In which k is the constant of proportionality.
In this problem, 7 out of 10 customers preferred the restaurants new spaghetti sauce, hence the constant is given by:
k = 7/10 = 0.7.
And the equation is:
y = 0.7x.
When x = 0, y = 0, which already eliminates graphs C and D. When x = 10, y = 7, which means that Graph A is the answer to this question.

Answer: First Option is correct.
Step-by-step explanation:
Since we have given that
Cost of per pound= $1.28
If a sack of cornmeal weighs = 4 pounds 12 ounces
First we need to convert ounces into pounds ,
as we know that ,
![1\ pound=16\ ounces\\\\1\ ounce=\frac{1}{16}\ pounds\\\\12\ ounces=\frac{12}{16}\ pounds=0.75\ pounds](https://tex.z-dn.net/?f=1%5C%20pound%3D16%5C%20ounces%5C%5C%5C%5C1%5C%20ounce%3D%5Cfrac%7B1%7D%7B16%7D%5C%20pounds%5C%5C%5C%5C12%5C%20ounces%3D%5Cfrac%7B12%7D%7B16%7D%5C%20pounds%3D0.75%5C%20pounds)
Now, total pounds of cornmeal is given by
![4+0.75=4.75\ pounds](https://tex.z-dn.net/?f=4%2B0.75%3D4.75%5C%20pounds)
Total cost for 4.75 pounds is given by
![4.75\times 1.28=\$6.08](https://tex.z-dn.net/?f=4.75%5Ctimes%201.28%3D%5C%246.08)
So, First Option is correct.

Step-by-step explanation:
For a polygon of N sides, the sum is
N*(180-360/N) = N*180 - 360 degrees
Subtract (120 +93 +108 +101) from 540 for your answer
