17. There are four drinks on sale: 20 ounce cup for $4.00, 12 ounce cup for $3.00, 10 ounce cup for $2.50, 8 ounce cup for $2.40. Which drink is the most expensive price per ounce?
Answer: B
The 8 ounce cup has the most expensive price per ounce.
To determine the most expensive drink in terms of price per ounce, the calculation reveals that the 8 ounce cup, priced at $2.40, results in a higher cost per ounce compared to the other options.
A) 12 ounce cup
The 12 ounce cup costs $3.00, which gives a price per ounce of $0.25. This is less expensive than the 8 ounce cup’s price per ounce, making it not the most expensive option.
B) 8 ounce cup
The 8 ounce cup is priced at $2.40, resulting in a price per ounce of $0.30. This is the highest price per ounce among all the drinks, confirming it as the most expensive option.
C) 10 ounce cup
The 10 ounce cup costs $2.50, leading to a price per ounce of $0.25. This is lower than the price per ounce of the 8 ounce cup, indicating it is not the most expensive choice.
D) 20 ounce cup
The 20 ounce cup is priced at $4.00, which results in a price per ounce of $0.20. This is the lowest price per ounce among the options, thus it cannot be considered the most expensive.
Conclusion
The 8 ounce cup is definitively the most expensive drink per ounce at $0.30, while the other options have lower costs per ounce. Therefore, the calculations show that all other choices do not exceed this price per ounce, affirming the 8 ounce cup as the correct answer.
