Mr Riddick’s car used 7 gallons of gasoline to travel 260 miles. After running over a huge object he noticed the car only traveled 190 miles on 8 gallons of gas. If the price of gasoline was $3.25 per gallon, how much money did Mr. Riddick save per mile before running over the huge object? (Round your answer to the nearest cent.)

Final answer:

Mr. Riddick saved $0.049 per mile on gas before running over a huge object, taking the difference between the cost per mile before and after the incident (rounded to the nearest cent).

Step-by-step explanation:

To calculate the amount of money Mr. Riddick saved per mile before running over the huge object, we first need to determine the cost per mile for both scenarios and then calculate the difference.

Initial scenario:

Before running over the object, Mr. Riddick's car used 7 gallons of gasoline to travel 260 miles.

Cost efficiency: Cost per gallon / miles per gallon

Cost per gallon: $3.25

Miles per gallon: 260 miles / 7 gallons

Cost per mile initial: $3.25 / (260 miles / 7 gallons) = $3.25 / (37.142857143 miles/gallon) = $0.0874 per mile

After incident:

After the incident, the car traveled 190 miles on 8 gallons of gas.

Miles per gallon: 190 miles / 8 gallons

Cost per mile after incident: $3.25 / (190 miles / 8 gallons) = $3.25 / (23.75 miles/gallon) = $0.1368 per mile

Money saved per mile before the incident:

Mileage cost difference: Cost per mile after incident - Cost per mile initial

Mileage cost difference: $0.1368 per mile - $0.0874 per mile = $0.0494 per mile

Mr. Riddick saved $0.049 per mile before running over the huge object (rounded to the nearest cent).
