1. The problem asks what the number 30 means in the context of the graph point (1, 30), where 1 represents grams of hamster food and 30 represents days. 2. The point (1, 30) means that it takes 30 days for Gabin's hamster to eat 1 gram of food. 3. This implies the hamster eats 1 gram every 30 days, or equivalently, the hamster's eating rate is 1 gram per 30 days. 4. Let's analyze the answer choices: - A: "Gabin's hamster eats a gram of food every 30 days." This matches the interpretation of the point. - B: "Gabin feeds his hamster once every 30 days." This is about feeding frequency, not the hamster's eating rate. - C: "Gabin's hamster eats 30 grams of food a day." This contradicts the point since it would mean the hamster eats much faster. 5. Therefore, the correct answer is A. Final answer: **A** Gabin's hamster eats a gram of food every 30 days.
