Answer:
The slope of the line that models this relationship is 0.50 US dollars per soda.
Step-by-step explanation:
At first we suppose the existence of a linear relationship between total cost (), measured in US dollars, and the number of sodas (
), measured in sodas, that is:
(1)
If we know that and
, then the slop of the line is:
The slope of the line that models this relationship is 0.50 US dollars per soda.
Given that <span>the area of the playground is 910 square feet, let the length of the playground be x, then the width of the playground is given by 
</span>Given that <span>the fence along three of the sides costs $5 per foot and </span>the fence along the fourth side, which will be made of brick, costs $15 per foot. <span>Let the side with the brick fence be the side which measures x feet.
</span>
Then the cost for fencing the entire playground is given by
For, minimum cost,
But x can't be negative.
Therefore, <span>the length of the brick fence that will minimize the cost of enclosing the playground is 21.33 feet.</span>
