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

Answer 1

To solve this problem, we can set up an equation to represent the situation.

Let x be the number of weeks it will take for Destiny's account to reach $343.

We know that Destiny opens a checking account with $100 and deposits $27 each week. So, the amount in her account after x weeks can be represented by the equation:

100 + 27x = 343

To solve for x, we need to isolate it on one side of the equation. Subtracting 100 from both sides, we have:

27x = 343 - 100

27x = 243

Finally, to solve for x, we divide both sides of the equation by 27:

x = 243/27

x = 9

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