i know the answer is D, but dont know how to solve it.1. If the nominal price of hockey tickets has increased from $100 to $150 and the consumer price index has risen from 160 to 200, then the real ticket prices have increased:
a) 50%.
b) 40%.
c) 30%.
d) 20%.

Hint - start by expressing the new price of tickets pre-inflation. Dollars today are worth 160/200 as much as before, so what is the equivalent price of tickets today using the old value of money?
