To determine the percent of change, we can use the formula:
\[
\text{Percent of Change} = \frac{\text{Change}}{\text{Original Price}} \times 100
\]
**Step 1: Calculate the change in price.**
The original price is $24.95, and the sale price is $14.97.
\[
\text{Change} = \text{Original Price} - \text{Sale Price} = 24.95 - 14.97
\]
Calculating that gives:
\[
\text{Change} = 24.95 - 14.97 = 9.98
\]
**Step 2: Set up the proportion.**
We want to set up the proportion:
\[
\frac{\text{Change}}{100} = \frac{?}{?}
\]
From our calculations, we know:
- Change = \(24.95 - 14.97\) (from option a)
- Original Price = \(24.95\) (from option c)
So we can complete the proportion as follows:
\[
\frac{24.95 - 14.97}{100} = \frac{9.98}{24.95}
\]
Therefore, the two answers that can be used in the proportion are:
- a: \(24.95 - 14.97\)
- c: \(24.95\)
So, the complete proportion is:
\[
\frac{9.98}{100} = \frac{24.95 - 14.97}{24.95}
\]
\[
\text{Percent of Change} = \frac{\text{Change}}{\text{Original Price}} \times 100
\]
**Step 1: Calculate the change in price.**
The original price is $24.95, and the sale price is $14.97.
\[
\text{Change} = \text{Original Price} - \text{Sale Price} = 24.95 - 14.97
\]
Calculating that gives:
\[
\text{Change} = 24.95 - 14.97 = 9.98
\]
**Step 2: Set up the proportion.**
We want to set up the proportion:
\[
\frac{\text{Change}}{100} = \frac{?}{?}
\]
From our calculations, we know:
- Change = \(24.95 - 14.97\) (from option a)
- Original Price = \(24.95\) (from option c)
So we can complete the proportion as follows:
\[
\frac{24.95 - 14.97}{100} = \frac{9.98}{24.95}
\]
Therefore, the two answers that can be used in the proportion are:
- a: \(24.95 - 14.97\)
- c: \(24.95\)
So, the complete proportion is:
\[
\frac{9.98}{100} = \frac{24.95 - 14.97}{24.95}

1. **Know the relationship**:
- 1 mile = 5,280 feet
2. **Determine how many feet are in 3.1 miles**:
- To find out how many feet are in 3.1 miles, we multiply the number of miles by the number of feet per mile:
\[
\text{Feet in 3.1 miles} = 3.1 \text{ miles} \times 5,280 \text{ feet per mile}
\]
Now perform the multiplication:
\[
\text{Feet in 3.1 miles} = 3.1 \times 5,280 = 16,368 \text{ feet}
\]
3. **Set up the proportion**:
You can structure your proportion as follows:
\[
\frac{? \text{ feet}}{3.1 \text{ miles}} = \frac{5,280 \text{ feet}}{1 \text{ mile}}
\]
4. **Fill in the blanks**:
Based on the information described, we can complete the proportion as follows:
- In the left part of the fraction, the quantity in feet corresponds to \( ? \) feet (which is 16,368 feet).
- On the right, the equivalent in miles is 3.1 miles and 5,280 feet.
Thus, the completed proportion is:
\[
\frac{16,368 \text{ feet}}{3.1 \text{ miles}} = \frac{5,280 \text{ feet}}{1 \text{ mile}}
\]
So, the answer to how many feet are in the 5K is:
