Answer 1

The price of one gallon is $2.90

Explanation:

The equation to calculate the price of one gallon could be calculated by multiplying the 8 gallons and the price of one gallon of gasoline (p), this is:

`8 gallons * p = 23.20`

So clearing the value of p, we have:

`(23.20)/(8 gallons)=2.90=p`

Finally, the price of one gallon is $2.90
