###Human: Jenny wants to sell some girl scout cookies and has the choice of two neighborhoods to visit.  Neighborhood A has 10 homes which each will buy 2 boxes of cookies.  Neighborhood B has 5 homes, each of which will buy 5 boxes of cookies.  Assuming each box of cookies costs $2, how much will Jenny make at the better choice of the two neighborhoods?, ### Assistant: First, we need to determine which neighborhood is the better choice by comparing the number of boxes sold. A has 10 houses which will buy 2 boxes each, meaning A will give Jenny 10*2=20 box sales
Neighborhood B has 5 homes which will each buy 5 boxes, meaning she will sell 5*5=25 boxes by going to that neighborhood.
Since 25>20, this means Jenny should choose neighborhood B.
Since Jenny earns $2 per box sold, this means she will earn 25*2=50 dollars by choosing neighborhood B. 
 So the answer is :  50
