Question

Room temperature ranges from 20 degrees Celsius to 25 degrees Celsius.Find the range of room temperature in degrees Fahrenheit. Use the formula F-32equals 1.8C to convert from the Celsius scale to the Fahrenheit scale.

Answer 1

F-32 = 1.8C

add 32 to each side

F = 1.8C +32

20 C

F = 1.8 (20) +32

F = 36+32

F = 68

25C

F = 1.8*25 +32

F = 45+32

F = 77

So 20C to 25C   is  68F to 77F
