​Dolbear's law states the relationship between the rate at which Snowy Tree Crickets chirp and the air temperature of their environment. The formula is ​T=50+n-40/4, where T is a temperature in degrees Fahrenheit and N is a number of chirps per minute. If T​=57°F, find the number of chirps per minute.

Answer:

Number of chirps per minute = 68

Step-by-step explanation:

Given:

​T = 50+ (N - 40)/4

where,

T is a temperature in degrees Fahrenheit

N is a number of chirps per minute

Find n when T = 57°F

​T = 50 + (N - 40)/4

57 = 50 + (N - 40)/4

57 - 50 = (N - 40)/4

7 = (N - 40)/4

Multiply both sides by 4

7 × 4 = (N - 40)/4 × 4

28 = N - 40

28 + 40 = N

68 = N

N = 68

Number of chirps per minute = 68
