Final answer:
By setting up and solving the equation 8.00 + 0.75m = 6.00 + 1.25m, where m represents miles, we find that the cost for a taxi ride would be the same after 4 miles for both companies.
Step-by-step explanation:
To determine at what mileage the cost of a taxi ride would be the same for both Company A and Company B, we need to set up an equation where the total cost of a taxi ride from both companies is equal. Company A's cost can be represented as 8.00 + 0.75m, where m represents the number of miles. Company B's cost can be represented as 6.00 + 1.25m.
Setting the two equations equal to each other gives us:
8.00 + 0.75m = 6.00 + 1.25m
To solve for m, we combine like terms:
8.00 - 6.00 = 1.25m - 0.75m
2.00 = 0.50m
Dividing both sides by 0.50 gives us:
m = 4 miles
Therefore, the cost for both companies would be the same after 4 miles.
