What was the daily average temperature in Darrtown in 2013?

Answer 1

You have been asking a lot to do with percents so I started working at leaning how to do them
65=100%
65/100=0.65
0.65=1%
3%=1.95
4.5%=2.925
65+1.95=66.95
66.95-2.925=64.025

64.025°F
I think I did it right

Answer 2

Answer:

The daily average temperature in Darrtown in 2013 was 63.93725 °F

Step-by-step explanation:

The average daily temperature in 2011 was  65° F.

In 2012, the temperature increased by 3%. So, the amount of increased temperature $=(65\times 3\%)= (65\times 0.03)= 1.95$ °F

So, the temperature in 2012 $=(65+1.95)= 66.95$ °F

In 2013, the temperature is decreased by 4.5%. So, the amount of decreased temperature $=(66.95\times 4.5\%)= (66.95\times 0.045)=3.01275$ °F

So, the daily average temperature in 2013 $=(66.95-3.01275)=63.93725$ °F
