Alice's take-home pay last year was the same each month and she saved the same fraction of her take-home pay each month. The total amount of money that she had saved at the end of the year was 3 times the amount of that portion of her monthy take-home pay that she did not save. If all the money that she saved last year was from her take-home pay, what fraction of her take-home pay did she save each month?
I don't understand the question. could anyone please explain?
lets say take home pay=P and saves X
