Answer: The answer is $12.80 or A
Step-by-step explanation:
First you take $2.40 and divide it by 3 ounces to find out the unit rate. So if you divide 2.4 by 3 you will get the answer 0.8, which tells us that 1 ounce of cinnamon is $0.80 and that our unit rate. So then we take $0.80 and multiply it by 16 to find out how much 1 pound of cinnamon cost because 16 ounces equal 1 pound and to find the cost you multiply by the unit rate. So now we do .8 multiplied by 16 which gives us 12.8 and that means that 1 pound of cinnamon cost $12.80.
