Question

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

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

Answer 1

The last gas station she stopped at she got 6.6 gallons and paid $20.39

If they lower the price by 6%, that means she would pay 94% of the original amount ( 100% - 6% = 94%)

Multiply the amount she paid by 94%:

20.39 x 0.94 = 19.17

She would pay $19.17 total.

Now divide that by the number of gallons bought:

19.17 / 6.6 = $2.90 per gallon ( Rounded to the nearest cent).
