<human>:  Christi saw twice as many black bears as white bears and 40 more brown bears than black bears in a national park. If the number of black bears in the park is 60, calculate the population of bears in the park.
<bot>: How many brown bears are there? ** If there are 60 black bears in the park and 40 more brown bears than black bears, there are 60+40 = <<60+40=100>>100 brown bears.
How many bears are there in the park? ** The number of black and brown bears in the park is 100+60 = <<100+60=160>>160
How many white bears are there? ** Twice the number of black bears as white bears means 60/2 = <<60/2=30>>30 white bears.
How many bears are there in the national park? ** The population of bears in the national park is 30+160 = <<30+160=190>>190
