Final answer:
The unit price per bottle of water is found by dividing the total cost by the number of bottles, resulting in approximately $0.14 per bottle, which is answer choice a.
Step-by-step explanation:
To find the unit price per bottle of water, divide the total cost of the case by the number of bottles. The case cost $4.99 and there are 35 bottles in the case.
The unit price calculation is as follows:
$4.99 ÷ 35 = $0.1425714286
Since we need to find the price in a form suitable for currency, we round the number to two decimal places, giving us approximately $0.14 per bottle of water. Therefore, the correct answer is a. $0.14.
