Final answer:
To determine the delivery distance, subtract the flower arrangement cost from the total cost and divide by the per mile rate. The calculation shows that the delivery was for 9 miles.
Step-by-step explanation:
To find out how many miles the flowers were delivered for a total cost of $34.50, when the local florist charges $30 for a flower arrangement and $0.50 per mile for delivery, we set up the following equation:
30 + (0.50 × number of miles) = 34.50
To solve for the number of miles, we follow these steps:
- Subtract the flat fee for the arrangement from the total cost:
34.50 - 30 = 4.50 - Divide the remaining amount by the cost per mile to find the number of miles:
4.50 ÷ 0.50 = 9
Therefore, the flowers were delivered for 9 miles.
