The function below allows you to convert degrees Celsius to degrees Fahrenheit. Use this function to convert 30 degrees Celsius to degrees Fahrenheit. F(c)= 9/5c + 32
30'C=___'F

30C = 86F

Using the question, F(c) = (9/5)C+ 32, substitute 30 in for Celsius in order to find the Fahrenheit equivalent.

F(c) = (9/5)(30) + 32

First, find (9/5):
(9/5) = 1.8

Next, multiple 1.8 by 30
1.8 * 30 = 54.

Finally, add 32.
54 + 32 = 86.

Therefore, 30 degrees Celsius is equal to 86 degrees Fahrenheit.
