Question

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)

amount; 1

weight; 10

amount; 10

weight; 1

Answer 1

weight; 10

Reason: The x-axis is the independent variable (dog weight), and a 10-lb scale is a sensible increment to show the ranges (<15, 15–50, 50+).
