Final answer:
Given the cost of five gallons of gas, we first find the cost per gallon and then use this to determine how many gallons can be purchased for $34.71, which is approximately 13 gallons.
This correct answer 3
Explanation:
To determine how many gallons of gas can be purchased for $34.71, we need to set up a proportion based on the given information that five gallons of gas cost $13.35. This problem relates to unit pricing and proportional reasoning, which are common topics in middle school math.
First, we calculate the cost per gallon by dividing the total cost by the number of gallons:
$13.35 ÷ 5 = $2.67 per gallon.
Now, to find out how many gallons can be purchased for $34.71, we divide the total cost by the cost per gallon:
$34.71 ÷ $2.67 = 13 gallons (approximately).
Therefore, the number of gallons of gas that can be purchased for $34.71 is closest to option iii) 13 gal.
