On a beautiful 68° day, Ernie was out on his daily walk in his neighborhood with his dog, Bert.

As they were walking, they passed by 14 people. Of the 14, only 5 said hello to Ernie.

Once home, Ernie checked his weather app and saw that the high temperature for the day was going to be nine times higher than the number of people that did not say hello to him while on his walk.

From the time Ernie started his walk, how many degrees warmer will it have to get in order to reach the expected high?

______ °

To solve the problem, let's break it down step by step.

### Step 1: Determine the number of people who did not say hello to Ernie.
- Ernie passed by 14 people in total.
- Of those 14, 5 people said hello to him.
- The number of people who did not say hello to Ernie is calculated as follows:

\[
14 - 5 = 9
\]

### Step 2: Determine the expected high temperature for the day.
- According to the problem, the high temperature is going to be nine times higher than the number of people who did not say hello.
- The number of people who did not say hello is 9, so the expected high temperature is:

\[
9 \times 9 = 81^\circ \text{F}
\]

### Step 3: Calculate how many degrees warmer it will need to get to reach the expected high.
- The current temperature is 68°F.
- The expected high temperature is 81°F.
- The difference between the current temperature and the expected high temperature is:

\[
81 - 68 = 13^\circ \text{F}
\]

So, it will need to get **13 degrees warmer** to reach the expected high.

### Final Answer:
\[
\boxed{13}^\circ \text{F}
\]

Here are 5 related questions:
1. How would the solution change if 7 people had said hello to Ernie?
2. What would the expected high temperature be if 10 people did not say hello?
3. How does the problem change if the current temperature was 72°F?
4. If the temperature had been given in Celsius, how would you convert it to Fahrenheit?
5. How many more people would need to say hello to Ernie for the expected high to be less than 70°F?

**Tip:** In temperature-related problems, always pay close attention to the units (Fahrenheit vs. Celsius) to avoid any conversion errors.

Learn how to calculate the temperature difference Ernie needs from his current walk temperature of 68°F to the expected high of 81°F. This problem involves basic arithmetic and understanding temperature differences. Suitable for students in Grades 5-6.
