Answer:
Step-by-step explanation:
The original price was 43 dollars
The new price is 55/100 * 43
The new price is 2365/100
The new price is 23.65 dollars
2365 came from multiplying 43 * 55 which is 2365
For this case we have that by definition, the equation of the line of the slope-intersection form is given by:

Where:
m: It is the slope of the line
b: It is the cut-off point with the y axis
According to the statement data we have:

Then, the equation is of the form:

We substitute the given point and find "b":

Finally, the equation is of the form:

Answer:

F(x) = -2.5x + 135...where x is the number of weeks, and f(x) = total weight
