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 8 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?
Pick:  A) 6/25  B) 5/16  C) 4/9  D) 3/7  E) 2/5
Let x be the fraction of her take-home pay that the worker saved.   Let P be the monthly pay.   12xP = 8(1-x)P   12xP = 8P - 8xP   20xP = 8P   x = 2/5   The answer is 2/5.
