The money invested in the account of gain was x = $ 9,000

The money invested in the account of loss was y = $ 8,000

Step-by-step explanation:

Solution:-

- Monica invested a total T = $ 17,000 in two of her accounts.

- Take the money invested in account A today = x

- Take the money invested in account B today = y

- The total money invested today is:

x + y = 17,000 ... Eq1

- After one year, the amount in each categorized by the following statement:

" The first account earned a rate of return of 14% (after a year) "

- The amount in account A after a year would be = ( 1 + gain/100 )*x

= ( 1 + 14/100)*x

= ( 1 + 0.14 )*x

= 1.14x

The account B:

" the second account suffered a 9% loss in the same time period "

- The amount in account B after a year would be = ( 1 - loss/100 )*y

= ( 1 - 9/100)*y

= ( 1 - 0.09 )*y

= 0.91*y

- The total amount of money in two accounts after one year would be:

Total money after a year = 1.14x + 0.91*y

- Given that the gain in one year was G = $540

G = Total money after one year - Total invested

540 = [ 1.14x + 0.91*y ] - 17,000

17,540 = 1.14x + 0.91*y Eq 2

- Solve the two equations Eq1 and Eq2 simultaneously:

x + y = 17,000

1.14x + 0.91*y = 17,540

x = $ 9,000 , y = $ 8,000

- The money invested in the account of gain was x = $ 9,000

- The money invested in the account of loss was y = $ 8,000
