Lucas's unwashed, dirty hand produces 947 CFU when swabbed onto a nutrient agar plate, while his alcohol-sanitized and air-dried hand produces 23 CFU on a swabbed agar plate. Calculate the change in CFU growth between Lucas's two skin-washing treatments, and convert it to percentage CHANGE (delta). What is the PERCENTAGE CHANGE (NOT % reduction!) in CFU ("%delta-CFU" or "%ACFU" = start with [CFUwashed - CFUunwashed)? (Bonus question for your notes: Is this an effective handwashing method?)
