Two ants, Arthur and Lily, have discovered a picnic and are bringing crumbs back to the anthill. Lily makes twice as many trips and carries one and a half times as many crumbs per trip as Arthur. If Arthur carries a total of a crumbs to the anthill, how many crumbs will Lily bring to the anthill, in terms of a?
Choose the correct choice from the following:  A) a/2  B) a  C) 3a/2  D) 2a  E) 3a
Lets do it by picking up numbers. Let Arthur carry 2 crumbs per trip, this means Lily carries 3 crumbs per trip. Also let Arthur make 2 trips and so Lily makes 4 trips.   Thus total crumbs carried by Arthur (a) = 2 x 2 = 4, total crumbs carried by Lily = 3 x 4 = 12. 12 is 3 times 4, so 3a
