The cost of a taxi ride includes a flat fee of $3.00 plus $2.50 per mile. Which equation represents the total cost (C) for a ride of (m) miles?

✓ Correct Answer: Option C

The flat fee ($3.00) is a constant, and the cost per mile ($2.50) is multiplied by the number of miles (m). The total cost (C) is the sum of these, matching the slope-intercept form C = 2.50m + 3.00.
