Lesson 2-6, Example 4 Check Understanding

1. You can use the number of chirps n a cricket makes in one minute to estimate the outside temperature F in degrees Fahrenheit. Transform the formula F = + 37 to find the number of chirps in terms of temperature. How many chirps per minute can you expect if the temperature is 60 F?
   1. n = 4F – 148; 102 chirps/min
   2. n = 4F – 148; 92 chirps/min
   3. n = 4F – 37; 203 chirps/min
   4. n = 4F + 37; 277 chirps/min
