http://www.ehow.com/facts_6027891_examples-equations-used-real-life.html 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.
