Your balance in 30 weeks will be $680.
To calculate Jossie's balance we can use the following formula:
Balance = Initial deposit + (Weekly deposit * Number of weeks)
Given:
Initial deposit = $230
Weekly deposit = $15
Number of weeks = 30
Putting these values into the formula, we get:
Balance = $230 + ($15 * 30)
Balance = $230 + $450
Balance = $680
Therefore, Jossie's balance after 30 weeks will be $680.
