Ed spoke to his cousin in Australia, who told him it was 25°C

that day. Ed wasn’t sure if that was hot or cold, so he converted the temperature to degrees Fahrenheit.

Use the formula F=95C+32
where F is degrees Fahrenheit and C is degrees Celsius. What is the temperature in degrees Fahrenheit?

To convert the temperature from degrees Celsius to degrees Fahrenheit using the formula \( F = \frac{9}{5}C + 32 \):

Given that \( C = 25 \):

\[ F = \frac{9}{5} \times 25 + 32 \]

Calculating \( \frac{9}{5} \times 25 \):

\[ \frac{9 \times 25}{5} = \frac{225}{5} = 45 \]

Now, add 32:

\[ F = 45 + 32 = 77 \]

Therefore, the temperature in degrees Fahrenheit is \( 77°F \).
