Coach park's car averages 33 miles per gallon of gasoline how many gallons of gas does he need for the trip? justify you answer

Since we don't know the length of the trip, we can't find an exact answer. 

However, we can write an expression for it. First, we let, T, represent the total number of miles for the trip.

Now, just divide T by 33. So our expression is T/33.

If you know the total miles of the trip, just divide it by 33 and you will have the answer.

Your answer is 5.

You can think of it as 7-2 because -2 is less than zero so you would have to subtract it from 7.
