Question

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?
