9 weeks
9 weeks
12.7 weeks
To solve this problem, we can use the equation:
Total amount in the account = Initial deposit + (Number of weeks * Weekly deposit)
We want to find the number of weeks, so we'll rearrange the equation:
(Number of weeks * Weekly deposit) = Total amount in the account - Initial deposit
(Number of weeks * 27) = 343 - 100
Number of weeks = (343 - 100) / 27
Number of weeks ≈ 9
Therefore, it will take approximately 9 weeks for Destiny's account to reach $343.
