The formula is: T=50 =N-40/4 where T is a temperature in degrees Farenheit and N is a number of chirps per minute. If T=58 degrees, find the number of chirps per minute. I'm showed the answer is 78 in my book, however I do not understand how this answer was solved. Please show me the steps to arrive at this answer.<BR>\n" );
