Final answer:
Max buys a total of 1830 grams of nuts, which is equal to 1 kilogram and 830 grams.
Step-by-step explanation:
To find the total mass of nuts bought by Max, we need to add the two masses together. Max buys 875 grams of nuts on Monday and 955 grams of nuts on Tuesday. Adding these two masses together, we get a total of 1830 grams of nuts. To convert this to kilograms and grams, we divide the total mass by 1000. So, the total mass of nuts Max buys is 1 kilogram and 830 grams.
