Final Answer:
1. Mr. Carson drives 20 miles for his round trip each day.
2. Mr. Carson drives 100 miles to and from work per week (20 miles/day * 5 days/week).
3. Mr. Carson uses 5 gallons of gas each week (100 miles/20 mpg).
4. It costs Mr. Carson $10 per week for gas ($2/gallon * 5 gallons).
5. With gas prices at $2.40 per gallon, Mr. Carson spends an extra $2 per week.
6. Mr. Carson's monthly cost for gasoline is $40 (4 weeks * $10/week).
Step-by-step explanation:
Mr. Carson's round trip to work is 20 miles each day, resulting in a daily commute of 40 miles (20 miles to work + 20 miles back home). For a standard 5-day workweek, he covers a total of 100 miles (40 miles/day * 5 days/week). Given his car's fuel efficiency of 20 miles per gallon, Mr. Carson consumes 5 gallons of gas each week (100 miles / 20 mpg).
The cost of gas at $2 per gallon translates to a weekly expense of $10 for Mr. Carson (5 gallons * $2/gallon). When gas prices increase to $2.40 per gallon, he incurs an additional $2 weekly. Therefore, his monthly gasoline cost, based on a 4-week month, is $40 (4 weeks * $10/week).
In summary, Mr. Carson spends $40 per month on gas. This calculation considers both regular and increased gas prices, providing a comprehensive understanding of his transportation expenses associated with fuel consumption.
