Question

The temperature at 8 AM was 43°F. AT IAM the temperature was 5°F warmer. At 8PM the temperature was 12°F colder than at I AM What was the temperature at 8PM?

Answer 1

The temperature at 11AM is 5 degree fahrenheit warmer that that at 8 AM, so temperature at 11 AM is,

`\begin{gathered} T=43^(\circ)F+5^(\circ)F \\ =48^(\circ)F \end{gathered}`

At 8 PM, the temperature was 12 degree fahrenheit colder than that at 11 AM. So temperature at 8 PM is,

`\begin{gathered} T^(\prime)=48^(\circ)F-12^(\circ)F \\ =36^(\circ)F \end{gathered}`
