Calculate the cost of gasoline for a 420-mile trip if your car averages 20 miles/gallon of gas, and the gas cost 0.95/gallon.

Answer : The cost of gasoline for a 420-mile trip is, $19.95
Solution :
As, 20 mile distance covered by 1 gallon of gas
So, 420 mile distance covered by [tex]\frac{420}{20}=21gallon[/tex] of gas
Now we have to calculate the cost of gasoline.
As, 1 gallon of gas cost = $0.95
So, 21 gallon of gas cost = [tex]\$0.95\times 21=\$19.95[/tex]
Therefore, the cost of gasoline for a 420-mile trip is, $19.95
the cost of gas is given as:
$0.95/gallon
the average of car is
20miles / gallon
The distance of trip is 420 miles
Thus the gas consumed for the trip is
Gas consumed = miles covered / car average
gas consumed = 420 / 20 = 21 gallon
The cost of gas will be = total gas consumed X price of each gallon
the cost of gas = 21 X $0.95 =$19.95
