My answers:
a. Yes
b. Y=4.35x

d. don't have one
I am no sure how to find the answers for c and d, please help
To find the answers for c and d, you need to analyze the given data points and look for patterns or relationships between weight and total cost.
c. To determine the weight, you need to look at the given data points for weight (4, 5, 46). You can observe that the weight has increased sequentially from 4 to 5 to 46 pounds. Hence, the weight is 46 pounds.
d. To find the total cost, you need to look at the given data points for the total cost ($17.40, $21.75, $200.10) and determine if there is a consistent pattern or equation. From the given data points, it is not clear if there is a linear relationship between weight and total cost.
However, based on the assumption that there is a proportional relationship between weight and total cost (as stated in answer a), you can find an equation to represent the relationship.
If the relationship is proportional, it means that the total cost is directly proportional to the weight. This can be expressed using the equation: C = k * w, where C represents the total cost, k is the constant of proportionality, and w represents the weight.
Using one of the given data points, such as (4, $17.40), you can substitute the values into the equation to solve for k:
17.40 = k * 4
k = 17.40 / 4
k = 4.35
Now that you have the value of k, you can use it to find the total cost for any given weight. For example, if the weight is 46 pounds, you can calculate the total cost using the equation:
C = 4.35 * 46
C ≈ 199.85
Therefore, the weight is 46 pounds (answer c), and the total cost is approximately $199.85 (answer d).
