Janet has 9 cards more than Brenda. Mara has twice as many cards as Janet. How many cards do they have in all if Mara has 40 cards less than 150?
Mara has 150 - 40 = <<150-40=110>>110 cards.
Janet has 110/2 = <<110/2=55>>55 cards since Mara has twice as many as Janet.
Brenda has 55 - 9 = <<55-9=46>>46 cards since Janet has 9 cards more than Brenda.
Therefore, they all have 110 + 55 + 46 = <<110+55+46=211>>211 cards.
