Oliwia is opening a bank account. She learns that there is a special promotion where if she deposits $3,000 and then makes no additional deposits or withdrawals, her account will earn $3 in interest per month. Write the equation of a linear function that models the relationship between number of months and total amount of money Oliwia will have in her account. (1 point)

0y = =3x + 3,000, where x is the number of months and y is the totall
amount of money Oliwia will have in her account.
•y = 3,000x + 3, where x is the number of months and y is the total amount of money Oliwia will have in her account.
• y =1,000x + 3, where x is the number of months and y is the total amount of money Oliwia will have in her account.
0y =3x + 1, 000, where x is the number of months and y is the total amount of money Oliwia will have in her account.

1 answer

To model the relationship between the number of months (x) and the total amount of money (y) in Oliwia's bank account, we can start with the initial deposit of $3,000 and add the interest earned each month.

Given that:

  • Initial deposit = $3,000
  • Interest earned per month = $3

The total amount in the account after \( x \) months can be represented by the equation:

\[ y = 3x + 3000 \]

where:

  • \( y \) is the total amount of money in the account after \( x \) months,
  • \( 3x \) represents the total interest earned after \( x \) months.

So the correct equation that models the relationship is as follows:

y = 3x + 3,000, where \( x \) is the number of months and \( y \) is the total amount of money Oliwia will have in her account.
