Given:
Initial amount = $8600
The amount in the account had decreased by 23.5%.
To find:
Decrease in amount and amount at the end of last year.
Solution:
The amount in the account had decreased by 23.5%. So,
Decreased amount = 23.5% of 8600
[tex]=\dfrac{23.5}{100}\times 8600[/tex]
[tex]=23.5\times 86[/tex]
[tex]=2021[/tex]
Now, the amount at the end of the last year is
Amount = Initial value - Decreased value
[tex]Amount=8600-2021[/tex]
[tex]Amount=6579[/tex]
Therefore, the decreased value is $2021 and the amount at the end of last year is $6579.
