In four weeks of commuting to school, it is expected the student saves a total of $13.32 if the prices went down from $2.49/gallon to $2.19.
<h3>How many gallons of gasoline does the student need each day and each week?</h3>
It is known, the total distance each day is 40 miles; moreover, the car requires 1 gallon of gasoline per 18 miles. Based on this, let's calculate the number of gallons of gasoline required:
- 40 miles / 18 miles = 2.22 gallons of gasoline
Now, if the student requires 2.22 gallons of gasoline everyday, the total number of gallons of gasoline per week is:
- 2.22 x 5 days = 11.1 gallons of gasoline
- 11.1 x 4= 44.4 gallons per month
<h3>How much will the student save?</h3>
Money spent with the regular gasoline price
- 44.4 gallons of gasoline x $2.49 = $110.55
Money spend with the new price:
- 44.4 gallons of gasoline x $2.19 = $97.23
- $110.55-$97.23 =$13.32
