Suppose that an office chair costs $50 in 2017, and $52.90 in 2018. Office chairs continue increasing in price, but this price increase decreases by 10 cents each subsequent year. Use anti-derivatives to express the price of a chair as a function of t, where t represents the number of years that have passed since 2017, so that t = 0 corresponds to the year 2017, t = 1 corresponds to the year 2018, and so on.
