Final answer:
To determine the distance at which both Speedy Cab and Friendly Cab would charge the same amount, we solve the equations C = 2.50 + 3.50d and C = 5.50 + 2.00d to find that the cost is the same at 6 miles.
Step-by-step explanation:
The question is asking to find at what distance the cost of two different cab companies would be the same. To solve this, we will set up two equations that represent the total cost for each cab company and then solve for the distance at which both costs are equal.
For Speedy cab, the equation for the total cost (C) as a function of distance (d) is:
C = 2.50 + 3.50d
For Friendly cab, the equation for the total cost (C) as a function of the distance (d) is:
C = 5.50 + 2.00d
To find when the cost is the same, we can set the two equations equal to each other and solve for d:
2.50 + 3.50d = 5.50 + 2.00d
Now we subtract 2.00d from both sides of the equation:
0.50d = 3.00
Finally, divide both sides by 0.50 to find the distance:
d = 6 miles
Therefore, after 6 miles, both cab companies would charge the same amount.
