To find the constant of proportionality that relates the cost in dollars to the number of gallons, we need to divide the cost by the number of gallons.
Constant of proportionality = Cost in dollars / Number of gallons
The cost in dollars is $13.56 and the number of gallons is 6. So,
Constant of proportionality = $13.56 / 6
= $2.26 per gallon
Therefore, the correct answer is B. $2.26 per gallon.
