Answer:

The constant of proportionality for this situation is 3.2

Explanation:

For the given situation we can say that, the amount spent to fill the gas directly varies with the number of gallons of gas filled.

We can say,


\$72.00=k* 22.5

where
k is the constant of proportionality which is nothing but the units rate of gas in dollars per gallon.

Dividing both sides by 22.5 to find
k


(72.00)/(22.5)=(k* 22.5)/(22.5)


k=3.2

Unit rate of gas = $3.2/gallon

∴ The constant of proportionality for this situation is 3.2.
