Final answer:
To find the cost of Mexican wine in dollars per ounce, one must convert the volume from liters to ounces and apply the exchange rate of 10 cents per peso to convert the price from pesos to dollars, resulting in approximately $0.63 per ounce.
Step-by-step explanation:
The question is asking to determine the cost in U.S. dollars per ounce for a 0.7-liter bottle of Mexican wine, given the price in pesos. To find the answer, we need to convert liters to ounces and then use the exchange rate to convert pesos into dollars.
First, we convert 0.7 liters to ounces knowing that 1 liter equals approximately 33.814 ounces. Thus, 0.7 liters is 0.7 × 33.814 ounces = 23.6698 ounces.
Next, we apply the provided exchange rate where 1 peso equals $0.10 USD. Therefore, 150 pesos is 150 × $0.10 = $15 USD.
Finally, we calculate the cost per ounce by dividing the total cost in dollars by the number of ounces. This gives us $15 / 23.6698 ounces ≈ $0.63 per ounce.
