Final answer:
The closest correct option is B). The unit price for a 6 oz package of cole slaw costing $1.25 is closest to $0.20 per oz, which is answer choice B.
Step-by-step explanation:
To calculate the unit price for a 6 oz package of cole slaw that costs $1.25, divide the total cost by the number of ounces. The calculation for this is $1.25 divided by 6 oz, which equals approximately $0.2083 per ounce. Since this is not an exact answer choice, we round to the nearest cent, which gives us $0.21 per oz, but since that is not one of the provided answers, the closest option is B. $0.20 per oz.
