Cassie is traveling 675 miles today to visit her brother and his family. So far, she has stopped for gas three times. At the first stop, she put in 7.1 gallons of gas and paid $23.79. At her second stop, she put in 5.8 gallons of gas and paid $19.08. And, at the third stop, 6.6 gallons and paid $20.39.

If the gas station that Cassie stopped at last lowers their price 6%, what will be their new price per gallon?

Final answer:

To determine the new price per gallon after a 6% reduction, first calculate the original price per gallon by dividing the total cost by the number of gallons. Then, find the amount of discount by multiplying the original price by 0.06. Subtract the discount from the original price to find the new price per gallon, which is approximately $2.90.

Step-by-step explanation:

The question involves calculating the new price per gallon after a discount at a gas station. Cassie paid $20.39 for 6.6 gallons on her third stop, which gives us the original price per gallon. To find the original price per gallon, we divide the total cost by the number of gallons, which is $20.39 / 6.6 gallons ≈ $3.09 per gallon. To calculate the new price after a 6% reduction, we multiply the original price by the percentage decrease: $3.09 * 0.06 = $0.1854. Subtracting this amount from the original price gives us the new price per gallon: $3.09 - $0.1854 = $2.9046. Therefore, after lowering their price by 6%, the gas station's new price per gallon will be approximately $2.90.

to know how much money per gallon for part 1), just divide the amount by the gallons, say 23.79/7.1 and check which one came out the cheapest
