. A 750-mL bottle of white wine costs $10.00. Your wine glasses hold 5 fluid ounces. a. How many fluid ounces are in 750 mL? b. How many glasses of wine can you serve from a 750-mL bottle? c. What is the cost per serving for this wine
The Correct Answer and Explanation is:
Answers:
a. There are 25.36 fluid ounces in 750 mL.
b. You can serve 5 glasses of wine from a 750-mL bottle (rounded down from 5.07).
c. The cost per serving is $2.00.
Explanation
To solve this problem, we need to understand basic unit conversions and how to calculate portions and cost per serving.
Part A: Convert 750 mL to fluid ounces
In the U.S. customary system, 1 milliliter (mL) is approximately equal to 0.033814 fluid ounces. So: 750 mL×0.033814=25.3605 fl oz750 \text{ mL} \times 0.033814 = 25.3605 \text{ fl oz}
Rounded to two decimal places, 750 mL equals 25.36 fluid ounces.
Part B: Determine the number of servings
Each wine glass holds 5 fluid ounces. To find out how many full glasses of wine are in 25.36 fl oz, divide: 25.36÷5=5.07225.36 \div 5 = 5.072
You can serve just over 5 glasses, but since you can’t serve a partial glass at a formal gathering, we round down to 5 full glasses.
Part C: Calculate cost per serving
The total cost of the bottle is $10.00. Since it yields 5 servings: $10.00÷5=$2.00 per serving\$10.00 \div 5 = \$2.00 \text{ per serving}
This tells us that each 5-ounce serving of wine costs $2.00.
Conclusion:
This simple wine-serving problem combines volume conversion, division, and cost analysis. It shows how understanding unit conversions and basic math is useful in everyday scenarios—such as budgeting for a dinner party or estimating how many guests can be served from one bottle. Whether you’re a host planning a party or simply curious about portion sizes, this type of calculation helps ensure fairness and cost-effectiveness.
