1.the temperature was 80∘f and then fell 20∘f. 2.the temperature was -13∘f and then rose 9∘f. 3.the temperature was -5∘f and then fell 8∘f.

The initial temperature is 80 °F.

The final termperature is 20°F.

During this period, fell 60 °F which represents a percentage of

We repeat the process for the rest.

From -13 °F to 9 °F, the temperature arose 22 °F, which is equivalent to

From -5 °F to 8 °F, the temperature fell 13 °F, which is equivalent to
