Danielle bought 2 boxes of tortilla chips and 3 boxes of unhealthy chips. Each box of tortilla chips had 4 bags, and each box of unhealthy chips contained 6 bags. How many more bags of unhealthy chips than tortilla chips did Danielle buy?
Danielle bought a total of 2 + 3 = <<2+3=5>>5 boxes of chips.
She bought 2 x 4 = <<2*4=8>>8 bags of tortilla chips.
She bought 3 x 6 = <<3*6=18>>18 bags of unhealthy chips.
She bought 18 - 8 = <<18-8=10>>10 more bags of unhealthy chips than tortilla chips. Answer: \boxed{10}.
