Answer 1

To calculate the average rate of change from 1985 to 1994, you need to know the prices of Kellogg's Corn Flakes for those specific years.

Let's assume you have the following hypothetical prices:

- 1985: $2.00
- 1994: $3.00

To find the average rate of change, you can use the formula:

\[
\text{Average Rate of Change} = \frac{\text{Change in Price}}{\text{Change in Time}} = \frac{\text{Price in 1994} - \text{Price in 1985}}{\text{Year 1994} - \text{Year 1985}}
\]

Plugging in the assumed prices:

\[
\text{Average Rate of Change} = \frac{3.00 - 2.00}{1994 - 1985} = \frac{1.00}{9} \approx 0.11
\]

However, since the exact prices have not been provided, you can replace the assumed prices with the actual prices from your data to calculate the exact average rate of change.

Once you have the specific prices for 1985 and 1994, calculate the average rate of change using the formula above. The options you provided seem to be in decimal form, so make sure your answer matches one of those forms after performing the calculations.
