Suppose x is the amount you want to save each week.
Then after 4 weeks you would have saved 4x. You want that to be at least 240, so 4x ≥ 240.
That's easy to solve by dividing both sides by 4.
x ≥ 60.

Sure...what else do you need? How about entering them as questions in the usual way, and I'll answer as many as I have time for.
