Question

Last year, Isabel opened an investment account with 6600 . At the end of the year, the amount in the account had decreased by 24.5%. How much is this decrease in dollars? How much money was in her account at the end of last year?

Answer 1

Isabel's investment account decreased by $1,617 due to a 24.5% loss, leaving her with an end-of-year balance of $4,983.

Step-by-step explanation:

Isabel experienced a decrease in her investment account due to a 24.5% loss. To calculate the decrease in dollars, we need to find 24.5% of $6,600. This is done by multiplying $6,600 by 0.245 (which is the decimal equivalent of 24.5%).

$6,600 \times 0.245 = $1,617

So, the amount of the decrease is $1,617. To determine how much money remained in her account at the end of the year, we subtract this decrease from the initial amount:

$6,600 - $1,617 = $4,983

Therefore, at the end of the year, Isabel's account balance was $4,983.

Answer 2

a. $1,617

b. $4,983

Step-by-step explanation:

a. The account suffered a decrease of 24.5% of the original sum of $6,600.

This amount in cash is:

= 24.5% * 6,600

= $1,617

b. If the account reduced by $1,617, the balance left is:

= 6,600 - 1,617

= $4,983
