Maria is baking cookies for Sally. Sally says that she wants 1/4 of her cookies to have nuts in them, 40% to have chocolate chips in them, and the remainder to have nuts and chocolate chips in them. When she adds nuts to the cookies, she uses 2 nuts per cookie. If she makes 60 cookies, how many nuts does she need?
35% of the cookies have nuts and chocolate chips because 100 - 25 - 40 = <<100-25-40=35>>35
60% of the cookies have nuts in them because 25 + 35 = <<25+35=60>>60
She makes 36 cookies with nuts in them because 60 x .6 =<<36=36>>36
She needs 72 nuts because 36 x 2 = <<36*2=72>>72
