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=9 over 5 C+32
where F is degrees Fahrenheit and C is degrees Celsius. What is the temperature in degrees Fahrenheit?

To convert 25°C to degrees Fahrenheit using the formula \( F = \frac{9}{5}C + 32 \):

  1. Substitute \( C = 25 \) into the formula:

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

  2. Calculate \( \frac{9}{5} \times 25 \):

    \[ F = 9 \times 5 + 32 = 45 + 32 = 77 \]

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

Answer: 77°F
