To find the number of weeks it will take Destiny's account to reach $343, we can set up an equation.
Let the number of weeks be represented by "x".
Starting with $100, she deposits $27 each week.
The equation to represent this situation is:
100 + 27x = 343.
To solve for x, we need to isolate the variable on one side of the equation.
Subtracting 100 from both sides, we have:
27x = 343 - 100,
27x = 243.
To solve for x, we divide both sides of the equation by 27:
x = 243/27 = 9.
Therefore, it will take her account 9 weeks to reach $343.
The correct answer is 9 weeks.
