Bake Sale
Four friends, Art, Roger, Paul and Trisha, bake cookies, and all cookies have the same thickness. The shapes of the cookies differ, as shown.
How many cookies will be in one batch of Trisha's cookies?
(A) 10(B) 12(C) 16(D) 18(E) 24
Anybody can help me on this problem? The answer was E. But, I think the given information in this question was insufficient.
Thanks!
