Answer 1

Answer: If you do 8400 - 24.5% you get 6342. Then if you do 8400 - 6342 you get 2058. So her account decreased by $2,058 and she had $6342 left in her account at the end of the year.

Answer 2

The dec

Step-by-step explanation:

Given that Lisa opened an investment account with $8400, at the end of the year, the amount in the account had decreased by 24.5%. We want to know how much the decrease is, and how much was in her account at the end of last year.

All we are required to find is what value is 24.5% of $8400

24.5% is the same as:

`(24.5)/(100)`

24.5% of $8400 is now:

`\begin{gathered} (24.5)/(100)*8400 \\ \\ =24.5*84 \\ =2058 \end{gathered}`

Therefore 24.5% of $8400 is $2058

This amount is the decrease.

Finally, at the end of last year, the amount in her account is:

$8400 - $2058 = $6342
