For this case, the first thing we must do is define variables.
We have then:
x: number of hours
y: Amount of scarf that Sara knits
We then have the following equation that models the problem:
The number of hours during the 8 days is given by:
Substituting the value of x in the ada equation we have:
Answer:

Step-by-step explanation:
The end behavior is found by following the arrows on the graph. Here, the right end of the curve tends to infinity in both x- and y-directions.
The left end of the curve tends to negative infinity as the value of x approaches 0 from above.
These observations are summarized in the attachment.
Answer:
It will cost $512.73
Step-by-step explanation:
9 in by 6 in sandbox cost $228
i.e., 9*6 = 54 in²
54 in² cost $228
1 in² will cost $228/54
≈ $4.22
If the new dimension is 13 1/2 in by 9 in
then area will be 13 1/2*9
27*9/2 = 121.5 in²
The cost of 121.5 in² will be
121.5*4.22 = $512.73
