A baker makes $N$ loaves of bread. For each loaf, he uses $B$ cups of flour at 5 cents per cup and $J$ grams of yeast at 6 cents per gram. The total cost of the flour and yeast for all loaves is $2.09. Assume that $B$, $J$, and $N$ are all positive integers with $N>1$. What is the cost of the yeast the baker uses to make the loaves?
