A dog boarding facility charges daily based on a dog’s weight. If the dog weighs under 15 lbs, the rate is $30. If the dog is between 15 and 50 lbs, it is $35. If the dog is 50lbs or more, the charge is $35 plus $3 for each additional 5 lbs over 50 lbs. Which of the following best defines the quantity and scale for the x-axis for a piecewise linear graph of the fee structure?(1 point)

Answer 1

The best choice to define the quantity and scale for the x-axis for a piecewise linear graph of the fee structure is:

weight; 10

This is because the x-axis represents the weight of the dog, with the rates changing based on specific weight thresholds. Additionally, using a scale of 10 provides a clear representation of the different weight categories for better visualization of the fee structure as weights increase.
