Human: 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? Assistant: 
How much does each head of lettuce cost? ** 2 heads of lettuce at $1 apiece is 2*$1=$<<2*1=2>>2.
How much does each tomato cost? ** 4 tomatoes at $0.50 apiece is 4*$0.5=$<<4*0.5=2>>2.
How much money does each customer spend on lettuce and tomatoes? ** Thus, each customer purchases $2+$2=$<<2+2=4>>4 in lettuce and tomatoes per month.
How much money will the store receive in sales of lettuce and tomatoes per month? ** Therefore, if 500 customers per month spend $4 on lettuce and tomatoes, then the store will receive $4*500=$<<4*500=2000>>2000 per month on sales of lettuce and tomatoes.
