Answer:
$70.56
Step-by-step explanation:
Lets convert the mixed number (trip length) to decimal.
We know 3/5 (by long division) is 0.6, so 705 3/5th = 705.60 miles
Now, let's come to the problem:
1 gallon = 28.8 miles (mileage)
or
$2.96 = 28.8 miles
To find cost per mile, we divide:
That means, it costs $0.10 per mile
Since we want to travel 705.60 miles, we multiply to find the cost:
$0.10 per mile * 705.60 miles = $70.56
