At Tom's workplace, the thermometer is reading 86 degrees Fahrenheit. When the temperature goes over 32 degrees Celsius, Tom must have an extra break.

He uses the formula below to calculate the temperature in °C.

16 degrees Celsius, with breaks at 172 degrees Fahrenheit.

Step-by-step explanation:

To calculate 86 degrees in Fahrenheit you need to take the 86 degrees you are given and first mulitply it by 5 over 9 (5/9). That will give you about 48 degrees. To finish solving it for celsius you then need to take your 48 and subtract 32, in which you would get 16. So, the temprature Tom needs to take a break at is 172 degrees Fahrenheit.
