Question

7. Richard wanted to make snow ice cream. His grandmother's recipe called for

7 cups of snow. However, when Richard went to make the ice cream his snow
melted a little and he ended up having to have 9 cups of snow. What is the
percent error of the recipe?

Answer 1

The percent error of Richard's snow measurements for his ice cream recipe is approximately 28.57%, calculated by dividing the difference between the expected and actual amounts by the original amount and multiplying by 100.

Step-by-step explanation:

The question asks for the percent error based on Richard having to use 9 cups of snow instead of the 7 cups called for in his grandmother's snow ice cream recipe. To calculate the percent error, we subtract the original amount from the new amount, divide by the original amount, and then multiply by 100 to get the percentage.

Here is the step-by-step calculation:

1. Find the absolute value of the difference between the expected value (7 cups) and the actual value (9 cups): |9 - 7| = 2 cups.
2. Divide this difference by the original value: 2 cups / 7 cups.
3. Convert this to a percentage by multiplying by 100: (2/7) × 100 = 28.57%

Therefore, the percent error in the recipe is approximately 28.57%.
