I thought we were talking about video games




1. POPULATION: The population of Bulgaria has been decreasing at an annual rate of 1.3%. If the population of Bulgaria was about 7,797,000 in the year 2000 predict its population in the year 2010.

0. There will be a cheesecake shortage

2. DEPRECIATION: Carl Gossell is a machinist. He bought some new machinery for about %125000. He wants to calculate the value of the machinery over the next 10 years for tax purposes. If the machinery depreciates at the rate of 15% per year, what is the value of the machinery (to the nearest $100) at the end of 10 years?

$0. It will be stolen by rats by then.

3. ARCHAEOLOGY: The half-life of a radioactive element is defined as the time is takes for one-half a quantity of the element to decay. Radioactive Carbon-14 is found in all living organisms and has a half life of 5730 years. Consider a living organism with an original concentration of Carbon-14 of 100 grams.

a. If the organism lived 5730 years ago, what is the concentration of Carbon-14 today?

Who cares?


b. If the organism lived 11460 years ago, determine the concentration of Carbon-14 today.
I thought we were talking about video games.


4. DEPRECIATION: A new car costs $32000. It is expected to depreciate 12% each year for 4 years and then depreciate 8% each year thereafter. Find the value of the car in 6 years.

No one will drive cars in 6 years with fuel going up like it is.


HILARIOUS!!!!!
