Select the correct answer.
Ms. Walker's class set up an online fund with a goal to raise $1,280 to go on a field trip. Ms. Walker starts the fund by depositing $5. Each week the balance of the fund is twice the balance of the previous week.

Which equation can be used to find the number of weeks, x, after which the balance of the fund will reach $1,280, and how many weeks will it take to reach the class goal?
