On a hot summer day, Jen is in a foreign country. She wonders which
temperature scale is used there, Celsius or Fahrenheit. Thermometers on
two local banks read 30. Since 30 Fahrenheit is below freezing,
o which scale is being used?

Which means that all temperatures below [tex]32\°F[/tex] are below the freezing temperature of water. Therefore, if Jen is in the Summer season, which is characterized by high temperatures, it is incoherent to think that the thermometer is using the Farenheit scale.

Now, [tex]30\°C[/tex] is in accordance with the high temperatures recorded in the summer season.

If we want to know how much [tex]30\°C[/tex] is in Farenheits, we must use the following conversion formula:

[tex](30\°C)(\frac{9}{5})+32=86\°F[/tex]
