James counted the number of alligators in various local bodies of water and graph the results how many fewer alligators are in bite swamp then chomp Lake and reptile Creek combined so down here we have this bar graph the James somehow survived to create after going to all these bodies of water and counting the alligators will help you is behind a fence or something so then we're asked how many fewer alligators are in bites swamp then in chomp Lake and reptile Creek combined so we need to know first how many are in chomp Lake and reptile Creek combined before we can figure out how many fewer are in bite swamp so let's look down here here's chomp Lake sounding super scary and it's bar lines up to six so there's six alligators in chomp Lake plus in reptile Creek if we go over here to reptile Creek this bar lines up to nine so there's nine alligators hanging out in reptile Creek six plus nine let's see nine plus one is ten so we can make our six into a five and a 1 9 plus 1 is 10 plus 5 more equals 15 so there's a total of 15 alligators in chomp Lake and reptile Creek combined now we can answer how many fewer than 15 are in bites swamp so bite swamp down here sounding the most dangerous of them all has a bar that lines up to 12 so 12 there's 12 alligators in bite swamp so how many fewer is 12 then the mountain chop Lake and reptile Creek combined 15 so how much fewer is 12 and 15 well if we have 15 and we take 12 away that leaves us with three there are three fewer alligators in bite swamp then there are in chomp Lake and reptile Creek combined
