To determine the total cost to have both dogs groomed, we need to use the information given about the piecewise linear function that likely represents the cost of grooming based on the weight of the dogs.
Assuming the function correlates the weight of the dogs to grooming costs (with the two dogs weighing 20 pounds and 45 pounds), we need to identify the respective costs.
If you can provide specific points or details from the graph, such as the cost for grooming a 20-pound dog and a 45-pound dog, I can then calculate the total grooming cost for both dogs. Please share that additional information to proceed.
