The Texas Instruments TI-2500 calculator did only the four basic arithmetic functions. What was its original price in 1972?
a) $75.50
b) $99.95
c) $149.95
d) $199.99
And my own follow-up question: What in the heck (I live in Utah now) did people do before calculators? Math?!

I'm guessing "D", $199
The answer is c. What is that in today's dollars, Rich? Can you figure it out for me? Without using a calculator??
Ignoring Moore's Law and assuming a 3% inflation rate, $149.95 would be equal to $421.94 today.
Here's the equation:
Present Value x (1+interest rate)^number of periods = Future Value
$149.95 x 1.03^35 = $421.94
And no, I would not want to do that without a calculator.
Nor would I want to do it with only a 4 function calculator (that raised to the 35th power part would get real old)
I love our family.
