Question

The last time Ms. Ward's car tank was filled, the odometer reading was 7,998 miles. The next time she filled up her vehicle with gas, the odometer reading was 8,308.

What was Ms. Ward's cost per mile for the time period? (remember, money always rounds to 2 decimal places!)

Answer 1

Explanation:

Miles travelled = 8,308 - 7,998 = 310 miles

Total cost = $26.79

Cost per mile
`=(26.79)/(310)` =0.0864

Ms. Ward's cost per mile is $0.09 (rounded to nearest cent).

Answer 2

$0.14

Explanation:

`8,308 - 7,998 = 310 \: miles`

We don't have information on how many gallons of gas Ms. Ward purchased, so we can't calculate the exact cost per mile. However, we can use the average fuel efficiency of her car to estimate the cost. Let's assume her car gets an average of 25 miles per gallon, which is a common fuel efficiency for a compact car.

To calculate how many gallons of gas she used, we can divide the number of miles driven by the fuel efficiency:

`(310 \: miles)/(25 \: miles _(gallon) ) = 12.4 \: gallons`

Assuming that the cost of gas was $3.50 per gallon, we can multiply the number of gallons used by the cost per gallon to find the total cost of gas:

`12.4 \: gallons * $3.50_(gallon) = $43.40`

To find the cost per mile, we can divide the total cost of gas by the number of miles driven:

`($43.40)/(310 \: miles) = $0.14_(mile)`

So Ms. Ward's cost per mile for this time period was approximately $0.14.
