A car used 8 gallons of gas to travel 340 miles a mechanic fixed the car. Then it used 7 gallons of gas to travel 350 miles. Gas cost $4.00 per gallon. How much less to the nearest cent per mile did it cost to run the car after mechanic fixed it

thx for everything i got an 100 !!!!!!!!!!

The answer is 0.01. because

(4) (8)=32 dollar
(32) (1/340)=0.09
And
(4) (7)=28 dollar
(28) (1/350)=0.08

0.09
- 0.08
--------------------
0.01
So the answer is 0.01 dollar

To find out how much less it cost to run the car per mile after the mechanic fixed it, we need to calculate the cost per mile for both situations (before and after the fix) and then find the difference between the two.

First, let's calculate the cost per mile before the mechanic fixed the car:
- The car used 8 gallons of gas to travel 340 miles, so the cost of gas in this case would be 8 gallons * $4.00/gallon = $32.00.
- Therefore, the cost per mile before the fix is $32.00 / 340 miles = $0.0941 per mile.

Now, let's calculate the cost per mile after the mechanic fixed the car:
- The car used 7 gallons of gas to travel 350 miles, so the cost of gas in this case would be 7 gallons * $4.00/gallon = $28.00.
- Therefore, the cost per mile after the fix is $28.00 / 350 miles = $0.08 per mile.

To find how much less it cost to run the car after the mechanic fixed it, we subtract the cost per mile after the fix from the cost per mile before the fix:
$0.0941 per mile - $0.08 per mile = $0.0141 per mile.

Therefore, it cost $0.0141 less, or 1.41 cents less, per mile to run the car after the mechanic fixed it.

8gal/340mi * $4.00/gal = $0.0941/mi

7gal/350mi * $4.00/gal = $0.0800/mi

340/8 = 42.5 mpg

350/7 = 50 mpg

Take it from there.
