In order to do this, replace all the numbers other than the 5. So, if you are looking for the first 5, make the 3, 6, 2, and other 5 to 0. You’ll get 5.00.
If the store has 35 total gallons, 2/3,14 gallons, of that is outdoor. Since you are looking for indoor, you subtract the outdoor gallons from the total amount which equal 3/5 or 21. Then you multiply 21•22=$462
