Answer :
Final answer:
To find the better deal, Tianna must calculate the unit prices by dividing the cost of each bottle by its volume in ounces. For the 16-ounce bottle at a cost of $2.409, the unit price is approximately $0.1506 per ounce. None of the answer choices given match this calculated unit price.
Explanation:
To determine which bottle of water offers the better deal, we need to calculate the unit prices and compare them. The unit price is calculated by dividing the total cost by the number of ounces. For the 16-ounce bottle costing $2.409, we calculate the unit price as follows:
Unit price = Total cost / Number of ounces
Unit price = $2.409 / 16 oz
Unit price = $0.1506 per ounce
When looking at multiple options, Tianna should compare this unit price to that of the other sizes to see which is more cost-effective. However, since the assignment is asking specifically about the 16-ounce bottle, the closest match to the calculated unit price among the options given is $0.905 per bottle, which is incorrect. None of the provided answers ($0.905, $1.25, $2.60, $3.15) correctly represent the cost of one 16-ounce bottle based on the unit price calculation. There might be a mistake in the question or the answer choices provided.
