Final answer:
The unit price of the first coffee option is $0.239 per ounce, and the second option is $0.217 per ounce. Comparing both, the second option is the better buy as it has a lower unit price.
Step-by-step explanation:
To find the unit price of the coffee options and determine which is a better buy, we need to divide the price of each option by the number of ounces it contains.
For the first option, 11.5 ounces for $2.75, the unit price is calculated as follows:
- $2.75 ÷ 11.5 ounces = $0.239 per ounce
For the second option, 34.5 ounces for $7.49, the unit price is calculated as follows:
- $7.49 ÷ 34.5 ounces = $0.217 per ounce
Comparing the unit prices, the second option at $0.217 per ounce is the better buy as it has a lower unit price compared to the first option at $0.239 per ounce.
Therefore, the correct answer is:
A. $0.239 per ounce, $0.217 per ounce
