Suppose that in 2017, a typical U.S. student attending a state-supported college bought 10 textbooks at a price of 100\( per book and enrolled in 25 credit hours of coursework at a price of 360\) per credit hour. In 2018, the typical student continued to purchase 10 textbooks and enrol in 25 credit hours, but the price of a textbook rose to 110\( per book, and the tuition price increased to 400\) per credit hour. The base year for computing a "student price index" using this information is 2017. What is the value of the student price index in 2017? In 2018? Show your work.
