Final answer:
One pound would cost $2.25.
Step-by-step explanation:
To find out the cost of one pound, we need to determine the price for one 1/4 pound unit. To do this, we divide the price of 3/4 pounds by 3, since 3/4 divided by 3 is 1/4. So, 6.75 divided by 3 is 2.25. Therefore, one pound would cost $2.25.
