Answer :
To convert degrees Celsius to degrees Fahrenheit, you can use the formula:
[tex]\[ F(c) = \frac{9}{5}c + 32 \][/tex]
Let's use this formula to convert 20 degrees Celsius to degrees Fahrenheit.
1. Start by inserting 20 for [tex]\( c \)[/tex] in the formula:
[tex]\[ F(20) = \frac{9}{5} \times 20 + 32 \][/tex]
2. Multiply [tex]\(\frac{9}{5}\)[/tex] by 20:
[tex]\[ \frac{9}{5} \times 20 = \frac{180}{5} = 36 \][/tex]
3. Add 32 to the result from step 2:
[tex]\[ 36 + 32 = 68 \][/tex]
Therefore, 20 degrees Celsius is equal to 68 degrees Fahrenheit.
The correct answer is:
C. 68
