Question

A thermometer at the park shows a reading of 86° Fahrenheit.

Answer 1

No he will not.
86 degrees F is 30 degrees C

Answer 2

Given:

• temperature recorded by thermometer is 86 degree Fahrenheit
• if temperature exceeds 32 degree Celsius, Tom must have a break
• the formula $F=1.8C+32$

To find: Does Tom get an extra break?

Solution: No, he does not need an extra break.

Explanation:

Given temperature is 86 degree Fahrenheit.

Using the equation $F=1.8C+32$, we substitute the temperature in Fahrenheit to find the value in Celsius.

So,

$F=1.8C+32\\\\86=1.8C+32\\\\1.8C=86-32\\\\1.8C=54\\\\C=\frac{54}{1.8} =30$

Therefore, as the temperature is only 30 degree Celsius (has not exceeded 32 degree Celsius), Tom does not need an extra break.
