the temp is 56 degrees farenheit. the temp decreases for 6 hours each hour the temp drops by 3 degrees Fahrenheit. then the temp goes up 12 degrees farenheit in one hour. what is the temp after 7 hours?

Respuesta :

Initial temperature: 56 °F

If the temperature drops by 3 °F per hour for 6 hours, then it drops 3*6 = 18 °F. Therefore, after 6 hours the temperature is: 56 °F - 18 °F = 38 °F

If next, the temperature goes up 12 °F in one hour, then after 7 hours the temperature is: 38 °F + 12 °F = 50 °F
