If chips cost 28 cents per ounce and a bag costs $3.75, how many ounces does the bag contain?

12.75 ounces
13.39 ounces
14 ounces
15 ounces

The correct answer is: 13.39 ounces

To determine how many ounces of chips are contained in the bag priced at $3.75, start by understanding the cost per ounce, which is 28 cents. First, convert the bag's cost into cents to facilitate easier calculation: $3.75 is equivalent to 375 cents (since 1 dollar = 100 cents). Next, divide the total cost of the bag by the cost per ounce to find the number of ounces: 375 cents ÷ 28 cents per ounce = approximately 13.39 ounces. Thus, the correct answer is that the bag contains about 13.39 ounces of chips. This calculation shows how to utilize unit costs to find the total quantity in terms of weight or volume, effectively demonstrating a critical application of quantitative reasoning in everyday pricing scenarios.
