2043  The Year That We All Turn Into ELVIS! 

Using this information we can calculate the growth factor for Elvis impersonators. If you've read The Perfect Sausage you'll know about the growth formula. We can adapt it to get this formula:

p = the number of Elvis impersonators in 1977.
e = the growth constant which is 2.718281828... r = the growth factor (we have to work this bit out) t = the number of years since 1977. 
Normally this formula would be applied to the interest you should earn from having money in the bank. P would be the premium (i.e. the money you start with), r would be the interest rate (usually as a decimal) and t would be the number of years you have the money in for.
With a little less conversation, a little more action if you please , we can work out that r = 0.2702005. (In other words the number of Elvis impersonators grows by just over 27% each year.)
Here's the bit that will leave you all shook up...
If you've got a suspicious mind, try working out how many Elvis impersonators there will be in the year 2043. Use the same formula, but put in t = 66 and you can use the value of r we've worked out, because that's the wonder of you.
Here's what the sum looks like:
You'll find that the number of Elvis impersonators in 2043 is 9,447,645,907. The population of the Earth in 2043 is expected to be slightly less than this number. So that means EVERYBODY on earth including people in the ghetto will be a guitar man just like Elvis...
