Mike fills his car's tank up with 20 gallons of regular gas at $2.09 per gallon. His car averages 25 miles per gallon. How many miles can Mike drive on a full tank of gas?

20 * 25 = 500 miles

Suppose a compact car uses 1 gallon of fuel for every 27 miles traveled. How would the graph for the compact car compare to the graph for the car shown?

To find out how many miles Mike can drive on a full tank of gas, we need to multiply the number of gallons in the tank by the car's average miles per gallon.

Step 1: Calculate the number of miles per gallon.
Mike's car averages 25 miles per gallon.

Step 2: Calculate the number of miles Mike can drive.
Mike fills his tank with 20 gallons of gas.
Therefore, Mike can drive 20 (gallons) * 25 (miles per gallon).

Let's calculate:
20 * 25 = 500 miles.

So, Mike can drive 500 miles on a full tank of gas.

*I forgot to add that, I always get a never ending decimal as the answer... please help :)
