Question

The formula F = 9/5C + 32 gives the temperature in degrees Fahrenheit for a given temperature in degrees Celsius. You are planning a trip to Australia for Winter break. The average temperature is 22 degrees Celsius. Would you bring your Winter coat? Justify using mathematics.

Answer 1

22 °C is a very fresh temperature, so I would not bring my winter coat

Explanation

$F=\frac{9}{5}C+32$

Step 1

22 °C , F?

Let

c=22

replace

$\begin{gathered} F=\frac{9}{5}C+32 \\ F=\frac{9}{5}(22)+32 \\ F=\frac{198}{5}+32 \\ F=71.6 \end{gathered}$

so, 22 °C is a very fresh temperature, so I would not bring my winter coat
