Final answer:
The cost of a taxi ride can be calculated using a formula: cost = $3 + $1.75 * m, where m represents the number of miles driven. For a 2-mile taxi ride, the cost would be $6.50.
Step-by-step explanation:
The cost of a taxi ride can be calculated using the formula: cost = $3 (pickup charge) + $1.75 * m (miles driven), where m represents the number of miles driven.
To calculate the cost of a 2-mile taxi ride, substitute the value of m into the formula: cost = $3 + $1.75 * 2 = $3 + $3.50 = $6.50.
For a taxi ride that is m miles long, the cost would be: cost = $3 + $1.75 * m.
