<human>:  Cary is trying to strip the ivy off a tree in her yard. She strips 6 feet of ivy every day, but the ivy grows another 2 feet every night. If the tree is covered by 40 feet of ivy, how many days will it take Cary to strip all the ivy off?
<bot>: How many feet of ivy does Cary remove each day? ** First find the net amount of ivy Cary removes each day by subtracting the ivy's growth from the amount she removes: 6 feet/day - 2 feet/day = <<6-2=4>>4 feet/day
How many days will it take Cary to strip all the ivy off? ** Then divide the total feet of ivy by the net amount Cary removes each day to find how many days it takes her to remove all the ivy: 40 feet / 4 feet/day = <<40/4=10>>10 days
