Suppose that in 2015, a typical U.S. student attending a state supported college bought 8 textbooks at a price of $90 per book and enrolled in 28 credit hours of coursework at a price of $400 per credit hour. In 2016, the typical student continued to purchase 8 textbooks and enroll in 28 credit hours, but the price of a textbook rose to $100 per book, and the tuition price increased to $440 per credit hour. The base year for computing a "student price index" using this info is 2015. The price index for any base year is 100. The value of the student price index in 2015 is

Answer:

$11,920

Explanation:

2015 prices:

8 textbooks x $90 = $720

28 credit hours x $400 = $11,200

total = $11,920

the base year, in this case 2015, will be used to adjust the relative prices of the goods and services purchased by students. E.g. for year 2016, the index based on 2015 should be (8 x $90) + (28 x $400) = $11,920 since the quantities didn't change, only the nominal prices.
