He would need to save $4 for 8 weeks.
Answer:

Step-by-step explanation:
We have been given that the variables y and x have a proportional relationship, therefore, we can represent the relationship between x and y as:
, where k is proportionality constant.
Let us substitute x=3 and y=15 in above equation to find the value of k.


Now let us substitute k=5 and y=4 in our proportionality equation to find the corresponding value of x.



Therefore, the value of x will be 0.8, when y equals to 4.
Answer:
- The y-intercept is - 372 and it means that if the manufacturers do not produce and sell any blenders they will have a loss of $ 372.
Explanation:
The polynomial that represents the function is:
Where the variable, x, represents the number of blenders produced and sold monthly, and P(x) is the monthly profit in dollars obtained for the sale of x blenders.
As for the question, the y-intercept is the point on the graph where the function crosses the y-axis, i.e. where the input of the function is x = 0.
Therefore, the y-intercept is the value of the function for x = 0, P(0), and it is found by substituting 0 for x in the polynomial function, which is shown next:
The meaning of this value is that the firm loses $372 when it does not produce and sell any blenders.
