Given:
A taxi service charges AED 10 plus AED 250 per kilometer for a trip to the airport.
The total charge is AED 135.
To find:
How far, in kilometers, is the trip to the airport?
Solution:
Let x km be the trip to the airport.
A taxi service charges AED 10 plus AED 250 per kilometer for a trip to the airport. So, total changes for x km trip is
[tex]T=10+250x[/tex]
The total charge is AED 135.
[tex]10+250x=135[/tex]
[tex]250x=135-10[/tex]
[tex]250x=125[/tex]
Divide both sides by 250.
[tex]x=\dfrac{125}{250}[/tex]
[tex]x=\dfrac{1}{2}[/tex]
[tex]x=0.5[/tex]
Therefore, the trip to the airport is 0.5 km.
