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.
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.
The number of black and brown bears in the park is 100+60 = <<100+60=160>>160
Twice the number of black bears as white bears means 60/2 = <<60/2=30>>30 white bears.
The population of bears in the national park is 30+160 = <<30+160=190>>190
