<human>:  Mason opens the hood of his car and discovers that squirrels have been using his engine compartment to store nuts. If 2 busy squirrels have been stockpiling 30 nuts/day and one sleepy squirrel has been stockpiling 20 nuts/day, all for 40 days, how many nuts are in Mason's car?
<bot>: How many nuts do the two busy squirrels gather per day? ** First find the number of nuts the two busy squirrels gather per day: 2 squirrels * 30 nuts/day/squirrel = <<2*30=60>>60 nuts/day
How many nuts do the two busy squirrels and the sleepy squirrel gather per day? ** Then add the number the sleepy squirrel gathers each day: 60 nuts/day + 20 nuts/day = <<60+20=80>>80 nuts/day
How many nuts are in Mason's car? ** Then multiply the number of nuts gathered daily by the number of days to find the total number of nuts gathered: 80 nuts/day * 40 days = <<80*40=3200>>3200 nuts
