An 18 fluid ounces bottle of lotion costs $10.99, what is the prices per fluid ounce?
The Correct Answer and Explanation is :
To find the price per fluid ounce of an 18 fluid ounce bottle of lotion costing $10.99, you need to divide the total price by the number of fluid ounces.
Calculation:
- Total Price: $10.99
- Total Volume: 18 fluid ounces
Now, you divide the total price by the total volume:
[
\text{Price per fluid ounce} = \frac{\text{Total Price}}{\text{Total Volume}} = \frac{10.99}{18} \approx 0.6105
]
This means the price per fluid ounce is approximately $0.61 when rounded to two decimal places.
Explanation:
Understanding how to calculate the price per unit of a product is essential for making informed purchasing decisions. In this case, by knowing the cost of an 18 fluid ounce bottle of lotion is $10.99, you can easily determine that each fluid ounce costs about $0.61. This unit price allows you to compare the cost-effectiveness of different lotion brands or sizes.
For example, if you come across another lotion that is sold in a 12 fluid ounce bottle for $8.99, you would calculate its price per fluid ounce similarly:
[
\text{Price per fluid ounce} = \frac{8.99}{12} \approx 0.7492
]
In this case, the second lotion costs approximately $0.75 per fluid ounce, which is more expensive than the first lotion. By calculating the price per fluid ounce, you can assess which product offers better value for your money.
Moreover, this knowledge can help you identify promotions or bulk purchase discounts effectively. Always consider the size and cost together to ensure you’re getting the best deal. Overall, understanding price per fluid ounce is a practical skill for budgeting and shopping, especially for products like lotions, shampoos, or any liquids sold in various sizes.
