The student begins with 500 rupees in her savings bank account. Every month, she receives an additional 150 rupees as pocket money. At the end of the first month, she will have 650 rupees. After the second month, she will have 800 rupees and the amount will continue increasing regularly. If n represents the number of months, then the total amount after n months can be written as 500 plus 150n rupees. This is a linear expression because the increase is constant every month.
