Final answer:
To find the total bill for 6 gallons of gas with a 10% tax when gas costs $2.50/gallon, you add the cost of the gas ($15.00) to the tax amount ($1.50) for a total of $16.50.
Step-by-step explanation:
To calculate the total bill, we first need to find the cost of 6 gallons of gas. Since gas costs $2.50 per gallon, the cost of 6 gallons would be $2.50 x 6 = $15.00.
Next, we need to calculate the amount of gas tax for 6 gallons. The gas tax is 10% per gallon, so for 6 gallons, it would be $2.50 x 0.10 x 6 = $1.50.
To find the total bill, we add the cost of gas ($15.00) and the gas tax ($1.50). The total bill would be $15.00 + $1.50 = $16.50.
The student asked about calculating the total bill for 6 gallons of gas with a 10% gas tax, when gas costs $2.50/gallon. First, we calculate the cost of gas before the tax by multiplying the cost per gallon by the number of gallons, which is $2.50 times 6. This equals $15.00. Then, we calculate the tax by taking 10% of $15.00, which is $1.50. Finally, we add the tax to the initial cost to get the total bill, so $15.00 plus $1.50 equals $16.50.
