<span>You can calculate percentages by first finding what 10% of a value is and then what 5 or 1% is. From there you can multiply to find multiples and then add to get the required percentage.</span>
Answer:
y=(5/3)x
Step-by-step explanation:
Since y varies directly with x, then the constant of proportionality is equal to k=y/x. Since y/x=20/12=5/3, then k=5/3. This means the equation to relate x and y is y=(5/3)x

as long as you get 5 for an answer, can be anything
10-5
It is c becase x<8 translates to x is less than 8

Step-by-step explanation:
<em>The question is incomplete as the solution to part A (or part A itself) is not given. To solve this, I will assume a value to the supposes solution to part A.</em>

From the question:
1 square foot is sold at $3.
This implies that:
p square foot will be sold at $3p.
So, total sales can be calculated using:
![Total = 3p](https://tex.z-dn.net/?f=Total%20%3D%203p)
Now assume that p is 10 square feet (from part A).
The total will be:
![Total = 3*10](https://tex.z-dn.net/?f=Total%20%3D%203%2A10)
![Total = \$30](https://tex.z-dn.net/?f=Total%20%3D%20%5C%2430)
