Question

If 4 gal of premium unleaded gasoline costs $15.04, how much would it cost to completely fill a tank whose capacity is 9-gal?

The cost to completely fill the tank is $

Answer 1

$33.84 cents

Explanation:

Given the following question:

4 gallons = 15.04
1 gallon = ?

How much for 9 gallons?

To find the answer we have to find how much one-gallon costs since we already know how much it costs for 4 gallons of this unleaded gasoline.


`15.04/4`

`15.04/4=3.76`

`=3.76`

One gallon of this gasoline costs $3.76 now we need to find how much it costs for 9 gallons.


`3.76*9=33.84`

`=33.84`

For nine gallons of gasoline it will cost you "$33.84 cents."

Hope this helps.
