Question

You buy 8 gallons of gasoline at p dollars per gallon and pay $23.20. Write an equation to find the price of one gallon of gasoline. Then find the price of one gallon of gasoline.

Answer 1

The equation is
8p=23.2
Where p is the price per gallon

To find the price per gallon, you just divide both sides by 8
P=23.2÷8
P=2.9 per gallon

Hope it helps!

Answer 2

The price of 1 gallon of gasoline is $2.90.

Explanation:

You buy 8 gallons of gasoline at p dollars per gallon and pay $23.20.

We get the expression:

`8p=23.20`

We can find one gallon as: p=
`(23.20)/(8)`

=> p = $2.90

Hence, the price of 1 gallon of gasoline is $2.90.
