    A bakery sells 5800 muffins in 2010. The bakery sells 7420 muffins in 2015. Write a linear model that represents the number y of muffins that the bakery sells x years after 2010.

    Find the number of muffins sold after 2010 through 2015:
    7,420 - 5,800 = 1,620

    Now, since the problem states a linear sales model, we need to determine the sales per year:
    1,620 muffins sold since 2010 / 5 years = 324 muffins per year.

    Build our linear model:
    y = 5,800 + 324x

    Reading this out loud, we start with 5,800 muffins at the end of 2010, and we add 324 more muffins for each year after 2010.
