But even so, linear equations can be handy enough for modelling simple everyday stuff. Example: Let's say you have $500 saved up, and you also have a part time job that nets you $200 a week. How much money will you have in a month? Two months? Using your knowledge of linear equations, you can set your wealth to be W(x) = 500 + 200x where x is number of weeks worked, and thus calculate your wealth at any point in time (x = 4 for one month, x = 8 for two months).
