How much is 16 dollars per a gallon

I think you are trying to find the unit rate.

It was 16 dollars for 3 gallons.

16:3

Divide both sides by 3.

5.333 repeating was how much one gallon was. Or, 5 and 1/3.

If each gallon is 16,

16*3 = 48

48 was the total amount.

I dont know what you’re asking for, so I gave you two answers. I hope one fits your needs.

16 dollars per gallon for three gallons is 48 dollars.

To find this all you have to do is 16 times 3
