To determine which brand is better to buy, we would determine the unit prices
The first option states that 2 pound s for $1.28
This means that 1 pound would be 1.28/2 = $0.64
For the second option, we would convert from ounce to pound
1 ounce = 0.0625 pounds
242 ounce = 242 * 0.0625 = 15.125 pounds
Therefore, for the second option,
15.125 pounds cost $19.36
1 pound = 19.36/15.125 = $1.28
We can see that the first option costs lesser per pound.
Therefore, option 1 is a better buy
