Final answer:
Anna's beetle will have eaten 1.04 grams more of dessert than the recommended amount over a seven-day week.
Step-by-step explanation:
To find out how many more grams of dessert Anna's beetle will have eaten than the recommended amount over a seven-day week, we need to calculate the total grams of dessert consumed and then subtract the recommended amount.
- First, we need to calculate the total grams of dessert consumed per day. Anna mixes 3.67 grams of pureed ants with a 1.43-gram blueberry, giving a total of 5.1 grams.
- Next, we divide the mixture into 30 equal parts, one for each day. So, each day the beetle consumes 5.1 grams / 30 = 0.17 grams of dessert.
- Lastly, we need to calculate the total grams of dessert consumed over a seven-day week. The beetle consumes 0.17 grams * 7 = 1.19 grams of dessert in a week.
To find the difference between the total grams of dessert consumed and the recommended amount, we subtract the recommended amount of 0.15 grams per day from the total grams consumed over a week: 1.19 grams - 0.15 grams = 1.04 grams.
Therefore, Anna's beetle will have eaten 1.04 grams more of dessert than the recommended amount over a seven-day week.
