IanStewart Am I missing something. Please help!!
I expect that Statement 2 was not copied correctly from the book - in the original post above, Statement 2 reads:
"2) It is possible to purchase four
more paintings at the gallery for a total of $2300."
That word "more" that I've highlighted makes no sense - "more" than what? There's no sensible way to interpret it. So I've interpreted Statement 2 to mean
"2) It is possible to purchase four (of the seven) paintings at the gallery for a total of $2300."
Then if we simply buy the cheapest three of those four paintings, we must spend less than the $1800 the question asks about.
I gather you're interpreting Statement 2 and the question to mean something like: "if we can buy four of the paintings for $2300, is it possible to buy the other three paintings for less than $1800?" If that's what Statement 2 meant, then yes, it is certainly not sufficient, since you have almost no information, under that interpretation, about the cost of the three paintings you're trying to buy.
If, on the other hand, the question has been faithfully transcribed from the source, then the source desperately needs editing. There are at least three other typos in it (there's a comma splice, 'painting' needs to be pluralized, and Statement 1 is missing a definite article) in addition to the problem I mention above. But I'd be surprised if the source contained that many errors, and I expect the interpretation I made above is either the one written in the book, or at least the one intended by the book.
