Answer
The price of gas per gallon = $3.60
Explanation
If it costs $46.80 to fill a 13 gallon gas tank.
We are asked to find the price of gas per gallon.
Let the price of 1 gallon of gas be x.
13 gallons = $46.8
1 gallon = x dollars
We can write a mathematical relationship by cross multiplying
13 × x = 1 × 46.8
13x = 46.8
Divide both sides by 13
(13x/13) = (46.8/13)
x = 3.6 dollars
Hope this Helps!!!
