Question

Marcus is buying his first tank of gasoline since he got his driver's license. Where he lives, gasoline is selling for between $1.20 and $1.40 per gallon. If he has $10.50 to spend on gas, how many gallons can he buy?

Answer 1

Marcus can buy between 7.5 and 8.75 gallons of gasoline with $10.50, depending on whether the price per gallon is $1.40 or $1.20, respectively.

Step-by-step explanation:

The student's question asks how many gallons of gasoline Marcus can buy with $10.50 when the price ranges from $1.20 to $1.40 per gallon. To calculate the maximum and minimum amount of gasoline he can purchase, we divide the total amount of money he has ($10.50) by the highest and lowest price per gallon.

• For the maximum price ($1.40 per gallon), we divide $10.50 by $1.40 to get approximately 7.5 gallons.
• For the minimum price ($1.20 per gallon), we divide $10.50 by $1.20 to get 8.75 gallons.

Therefore, Marcus can buy between 7.5 and 8.75 gallons of gasoline with his $10.50.
