Arithmetic Applied problems
Let $R be the novelist's royalties last year, and let $Y be the yearly fee paid to the publicist. Determine whether 0.15R > 0.05R + Y, or equivalently, whether R > 10Y.
No information is given that allows us to determine whether R is greater than 10Y = 10(2,000) = 20,000; NOT sufficient. No information is given that allows us to determine whether 3,500n is greater than 10Y, where n is the number of novels; NOT sufficient.
Given (1) and (2) and letting n be the number of novels, we are to determine whether 3,500n > 20,000. If n = 1, then the answer is NO. However, if n = 10, then the answer is YES.
The correct answer is E;both statements together are still not sufficient.
