Nakida read that the number of times a
cricket chirps depends on the
temperature of the air. The scientists
found that the number of chirps per
minute is equal to 0.23 times the
temperature of the air, in degrees
Fahrenheit, plus 40.
Write an equation that represents
the number of times a cricket
chirps given the temperature in
degrees Fahrenheit.
