Question

On a certain day, the temperature is - 12/5 oF. After 2 days, the temperature decreases by a factor of 7/3. Find the temperature.

Answer 1

On a certain day: Temperature = -12/5 degree Fahrenheit

`T_0=-(12)/(5)^(\circ)F^{}`

2 days later, the temperature decreased by a factor of 7/3

`T=T_0*(7)/(3)`

The temperature is calculated as shown below:

`\begin{gathered} T=-(12)/(5)*(7)/(3) \\ T=-(12*7)/(5*3) \\ T=-(84)/(15)=-(28)/(3) \\ T=-(28)/(3) \end{gathered}`

Therefore, the answer is
