Solve the following real-world problem: Destiny opens a checking account with $100 and then deposits $27 each week. How many weeks will it take her account to reach $343?

1 answer

To solve this problem, we first need to determine the difference between the initial amount in the account and the desired amount.

Desired amount = $343
Initial amount = $100

Difference = Desired amount - Initial amount = $343 - $100 = $243

Since Destiny deposits $27 each week, we need to divide the difference by the weekly deposit amount to find out the number of weeks it will take to reach $343.

Number of weeks = Difference / Weekly deposit amount = $243 / $27 = 9 weeks

Therefore, it will take Destiny 9 weeks to reach $343 in her account.
