Elois needs 4 bananas to make 1 loaf of banana bread.  On Monday, she makes 3 loaves of banana bread.  On Tuesday, she makes twice as many loaves of banana bread as Monday.  How many bananas did she use to make all the banana bread?
On Tuesday, Elois makes 3 x 2 = <<3*2=6>>6 banana breads.
She makes a total of 3 + 6 = <<3+6=9>>9 banana breads.
She uses 9 x 4 = <<9*4=36>>36 bananas to make all the banana breads.
