For example : Soon or later, all of us use the service of a taxi driver
Taxi drivers usually charge a an initial fixed fee as part of using their services. Then, for each mileage, they charge a certain amount
Say for instance, the initial fee is 4 dollars and each mileage cost 2 dollars
The total cost can be modeled with an equation that is linear.
Let y be the total cost
Let N be number of mileage
Total cost = 4 + cost for N miles
Notice that cost for N miles = N×2
Therefore, y = 4 + N×2
Say for instance, a taxi driver takes you to a distance of 20 miles, how much money do you have to pay using y = 4 + N×2 ?
When N = 20, Y = 4 + 20×2 = 4 + 40 = 44 dollars
Now, let's ask the question the other way around!
If you pay 60 dollars, how far did the taxi driver took you?
This time y = 60
Replacing 60 into the equation gives you the following equation:
60 = 4 + N×2
It is not obvious to see that N = 28.
I saw this one, I was looking for a less detailed example. but thank you!
