Elena is tracking her monthly expenses on a linear graph, where her total expenses (in dollars) are represented as a function of the number of months since January. She starts the year with an initial expense of $200 in January and plans to increase her expenses by $50 each month due to rising costs.
Let $$x$$ represent the number of months since January, and let $$E(x)$$ represent Elena's total expenses in dollars for month $$x$$. Based on this information, determine Elena's total expenses in dollars after 5 months.
