I read once that you can figure out what the temperature is in degrees F (Fahrenheit) by counting the number of chirps that a cricket makes in 15 seconds. I couldn't remember the formula, but I did find some data.

chirps in 15 seconds

temperature in F

Use your TINspire™ to help you answer these questions:
 What's the temperature when a cricket is chirping 164 times a minute?
 Write a formula that could be used to predict the temperature given the number of chirps per 15 seconds. Note: Use "c" for chirps and "t" for temperature.
