Biologists have noticed that the chirping of crickets of a certain species is related to temperature, and the relationship appears to be very nearly linear. A cricket produces 112 chirps per minute at 71 degrees Fahrenheit and 172 chirps per minute at 88 degrees Fahrenheit.

Find a linear equation that models the temperature $T$ as a function of the number of chirps per minute $N$.
$T(N) =$

If the crickets are chirping at 160 chirps per minute, estimate the temperature:
Temperature =
