Question

Crickets and Temperature Biologists have observed that the
chirping rate of crickets of a certain species is related to temperature, and the relationship appears to be very nearly
linear. A cricket produces 120 chirps per minute at 70F and
168 chirps per minute at 80F.
(a) Find the linear equation that relates the temperature t and
the number of chirps per minute n.
(b) If the crickets are chirping at 150 chirps per minute,
estimate the temperature.
