A worker'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 4 times the amount of that portion of her monthly 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?	Choose the correct choice from the following answers
A) 1/3	B) 1/4	C) 1/5	D) 1/6	E) 1/7
Let x be the fraction of her take-home pay that the worker saved.   Let P be the monthly pay.   12xP = 4(1-x)P   12xP = 4P - 4xP   16xP = 4P   x = 1/4   The answer is 1/4.
