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

1 answer

We can set up the equation as follows:

100 + 27w = 343

where w represents the number of weeks.

To solve for w, we can subtract 100 from both sides:

27w = 343 - 100
27w = 243

Then, divide both sides by 27:

w = 243 / 27
w = 9

It will take Destiny 9 weeks for her account to reach $343.
