Javier Clark · Answer 1

Given the choices, we have that we need to extrapolate data from one street to the whole neighborhood. If we know that there are y mailboxes in one street, then to account for the mailboxes in all streets, we need to multiply by the number of streets. Hence, the correct answer is A. B and C are wrong because they give a ratio rather than a total amount while the formula in D involves the quantity we want to find (number of boxes in the neighborhood).
