Final answer:
To find the cost of 12 gallons of gas, we calculate the rate of 4 dollars per gallon by dividing 8 dollars by 2 gallons and then multiply by 12 gallons, resulting in a total cost of 48 dollars.
Step-by-step explanation:
The question asks how much 12 gallons of gas will cost Mr. Artenstein if he pays 8 dollars per 2 gallons.
To find the cost for 12 gallons, we first determine the cost per gallon by dividing 8 dollars by 2 gallons, which gives us the rate of 4 dollars per gallon. We then multiply the rate per gallon by the number of gallons Mr. Artenstein wants to purchase, in this case, 12 gallons.
Multiplying 4 dollars per gallon by 12 gallons gives us the total cost of 48 dollars for 12 gallons of gas.
