Answer:
The average percent change each month will be = 6.4%
Step-by-step explanation:
In the first month, the price was $348 and the decrease in value is $20.88.
So, the percent change in value is [tex]\frac{20.88}{348}\times 100\% = 6\%[/tex].
Now, in the second month, the price was $(348 - 20.88) = $327.12 and the decrease in value is $20.88.
So, the percent change in value is [tex]\frac{20.88}{327.12}\times 100\% = 6.38\%[/tex].
Again, in the third month, the price was $(327.12 - 20.88) = $306.24 and the decrease in value is $20.88.
So, the percent change in value is [tex]\frac{20.88}{306.24}\times 100\% = 6.82\%[/tex]
Therefore, the average percent change each month will be = [tex]\frac{6 + 6.38 + 6.82}{3} = 6.4\%[/tex] (Answer)
