#"difference" = $3/80 x#

In each instant we are talking about cost per person. So we need the difference between these two values.

Let the difference be #d#

#d=x/10-x/16#

#d=[x/10xx8/8]-[x/16xx5/5]#

#d=[(8x)/80]-[(5x)/80] #

#d=(3x)/80#

but the difference in in dollars

#"difference" = $3/80 x#
