Three ounces of cinnamon cost $2.40. if there are 16 ounces in 1 pound, how much does cinnamon cost per pound?

So we want to know how much does cinnamon cost per pound if we know that 3 ounces cost 2.4$ and that there is 16 ounces in a pound. So lets first find the price of one ounce of cinnamon and lets call it x. x=2.4$/3=0.8$ So one ounce costs 0.8$. Now since there are 16 ounces in a pound, 1 pound = 16x or 16*0.8$=12.8$. So the cost of cinnamon per pound is 12.8$
