Question

1. todays temperature kept on changing throughout the day. at 7 am it was 56°f outside. the temperature rose 4°f, dropped about 5°f, increased 2°f, and then went up another 5°f. what was the final temperature at the end of the day? use the number line below to determine your answer. what is the final temperature at the end of the day? ____ °f

Explanation:

Step1: Start with initial temperature

The initial temperature is $56^{\circ}F$.

Step2: Account for first change

It increased by $4^{\circ}F$, so the temperature becomes $56 + 4=60^{\circ}F$.

Step3: Account for second change

It dropped by $5^{\circ}F$, so the temperature is $60- 5 = 55^{\circ}F$.

Step4: Account for third change

It increased by $2^{\circ}F$, so the final temperature is $55+2 = 57^{\circ}F$.

Answer:

$57^{\circ}F$
