The Inflation Problem. If a person makes $30,000 in 2004 and the inflation rate is 4% annually, how much is this salary worth in the year 2008 (in terms of 2004 dollars)?

Would I just add by 4% for 4 years?

No, his salary would be worth LESS than $30,000 in the year 2008

value = 30000(1 - .04)4 = $25,480.40

just noticed a typo

my last line should have been

value = 30000(1 - .04)^4 = $25,480.40

if a movie ticket cost $8 for admission, what would the cost be in 7 years, assuming an inflation rate of 3%?
