A novelist pays her agent 15% of the royalties she receives from her novels. She pays her publicist 5% of the royalties, plus a yearly fee. Did the novelist pay more to her agent last year than she paid to her publicist?Let the total royalties the novelist received last year be R.
Agent’s pay = 15% of R = 0.15R
Publicist’s pay = 5% of R + yearly fee = 0.05R + fee
We need to know whether:
0.15R > 0.05R + fee
0.10R > fee
So we need enough information to compare 10% of the total royalties with the yearly fee.
(1) The publicist's yearly fee is $2,000.
Now we need to know whether 0.10R > 2000, or equivalently whether R > 20000. But we do not know R. Not sufficient.
(2) The novelist earned an average of $3,500 in royalties last year on each of her novels.
This gives:
R = 3500 * number of novels
But we do not know how many novels she earned royalties on, and we also do not know the publicist’s yearly fee. Not sufficient.
(1)+(2):
From (1), fee = 2000.
From (2), R = 3500n, where n is the number of novels.
We need to know whether:
0.10(3500n) > 2000
n > 5.7...
That means we need to know whether n is at least 6. But the number of novels is still unknown. Not sufficient.
