Question

landis and her father took a taxi cab that charges $2.70 per mile plus $1.25 for each passenger, and they paid a total of $24.10. how can landis correctly determine the number of miles the taxi traveled? she can find the charge for the number of miles driven by adding $2.50 to the total cost, $24.10. then, she could divide the sum by 2.70. she can find the charge for the number of miles driven by subtracting $2.50 from the total cost, $24.10. then, she could divide the difference by 2.70. she can find the charge for the number of miles driven by dividing the total, $24.10, by 2.70. then she could subtract $2.50 from the quotient. she can find the charge for the number of miles driven by dividing the total, $24.10, by 2.70. then she could add $2.50 to the quotient.

Explanation:

Step1: Calculate passenger charge

There are 2 passengers, so total passenger charge is $2 \times 1.25 = 2.50$

Step2: Isolate mileage cost

Subtract passenger charge from total cost: $24.10 - 2.50$

Step3: Solve for total miles

Divide mileage cost by per-mile rate: $\frac{24.10 - 2.50}{2.70}$

Answer:

B. She can find the charge for the number of miles driven by subtracting $2.50 from the total cost, $24.10. Then, she could divide the difference by 2.70.
