Nate and his friends are building a skateboard ramp for an upcoming contest. The length of the ramp on the blueprint is 7.6 inches. If the scale on the blueprint is 1 inch to 4 feet, what is the actual length of the ramp?
 A. 
15.2 feet
 B. 
19 feet
 C. 
30.4 feet
 D. 
38 feet

To find the actual length of the ramp, we need to use the scale provided. The scale on the blueprint is 1 inch to 4 feet. Given the length of the ramp on the blueprint is 7.6 inches, we can calculate the actual length as follows:

### Step-by-Step Calculation

1. **Determine the scale conversion:**
   - 1 inch on the blueprint corresponds to 4 feet in actual length.

2. **Calculate the actual length:**
   - Actual length = Blueprint length × Scale factor
   - Actual length = 7.6 inches × 4 feet/inch

\[
\text{Actual length} = 7.6 \, \text{inches} \times 4 \, \text{feet/inch} = 30.4 \, \text{feet}
\]

Therefore, the actual length of the ramp is:
\[
\boxed{30.4 \, \text{feet}}
\]
