conversations.value: I'm stuck on this math problem: Village Foods sells good food at a fair price.  Their specialty is fresh vegetables.  If they get 500 customers per month, and each customer purchases 2 heads of lettuce for $1 each and 4 tomatoes for $0.5 apiece, then how much money, in dollars, will the store receive in sales of lettuce and tomatoes per month?
  Can you help?

conversations.value: 2 heads of lettuce at $1 apiece is 2*$1=$2.
  4 tomatoes at $0.50 apiece is 4*$0.5=$2.
  Thus, each customer purchases $2+$2=$4 in lettuce and tomatoes per month.
  Therefore, if 500 customers per month spend $4 on lettuce and tomatoes, then the store will receive $4*500=$2000 per month on sales of lettuce and tomatoes.
