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)

The x-axis should represent the dog's weight (in pounds). Use a scale of 1 (one unit = 1 lb) so you can accurately show the piecewise segments and the $3 increase for each 5-lb increment.
