Question

Richard bought rolls for a BBQ. He bought dozen wheat rolls and dozen snowflake rolls. If dozen rolls were eaten at the BBQ, how many dozen rolls does Richard have left?

Answer 1

Richard bought 12 + 12 = <<12+12=24>>24 rolls.
There are 24 rolls / 12 = <<24/12=2>>2 dozen rolls.
Richard has 2 - 1 = <<2-1=1>>1 dozen rolls left. Answer: \boxed{1}.
