You're going on a 1211-mile trip, and your car gets about 29 miles per gallon. Gas prices along your route average $1.99. Estimate the cost of gasoline for this trip by rounding the distance to 1200 miles, the mileage to 30 miles per gallon, and the cost of gas to $2.00 per gallon. Calculate the answer without using estimation and compare the two results. (Round your answers to the nearest cent.)
