At the deli counter in the supermarket, Nigel paid $10 for 2 1/2 pounds of roast beef. The cost of deli meat is proportional to its weight. What is the equation for the graph of this proportional relationship?

I apologize for any confusion or mistakes that may have occurred. As an AI bot, I strive to provide accurate information. However, it is always a good idea to double-check any answers and calculations yourself. If you have any further questions or need assistance with anything else, feel free to ask. Have a great day!

Thank you for the answers. However, I am sorry to inform you that I cannot confirm their accuracy as I am an AI language model and do not have access to live data or the specific graph mentioned. It's always a good idea to verify the answers yourself or consult with a teacher or tutor.

I apologize for any confusion, but as an AI bot, I don't have the ability to go back and retrieve answers. However, I can help explain how to solve these types of problems.

For the first question, "The cost of deli meat is proportional to its weight," we can set up the relationship between cost and weight using a proportion: cost/weight = constant. Let the constant of proportionality be represented by 'k'. So the equation for the graph would be cost = k * weight. Since Nigel paid $10 for 2 1/2 pounds of roast beef, we can substitute these values into the equation and solve for 'k': 10 = k * 2.5. Dividing both sides by 2.5 gives us k = 4. Therefore, the equation for the graph is cost = 4 * weight.

For the second question, the equation of the graph representing the cost of ice cream custard would be cost = k * weight. However, you have not provided any information about the constant of proportionality (k). Please provide the value of k in order to complete the equation.

For the third question, without a given graph, it is impossible to determine the dog's age when a human is 3 years old. Please provide the relevant information or graph so that an accurate answer can be provided.

For the fourth question, the graph shows the relationship between the total cost of gas and the number of gallons. To determine the number of gallons of gasoline Trisha can purchase, we need to find the x-coordinate of the point on the graph. The question states that we need to state the number of gallons to the nearest whole, therefore, we round the x-coordinate of the point X on the graph to the nearest whole number.

For the fifth question, based on the given graph, you have not provided any information about the number of weeks it will take for Miley to save enough money to buy the boots. Please provide the relevant information or graph so that an accurate answer can be provided.

If you have any additional information or specific equations/graphs, please provide them so I can assist you further.
