A consumer advocacy group recorded several variables on 140 models of cars. The resulting information was used to produce the following regression output that relates the city gas mileage (in mpg) and the engine displacement (in cubic inches).

The regression equation is mpg:city=33.4 - 0.0624 displacement

Predictor Coefficient SE Coef. T p-value Constant 33.4 0.7762 43.00 0.0000 displacement -0.0624 0.003810 -16.38 0.0000 S=3.13923 R-sq=66.0%

We have a car that has an engine with 150 cubic inches.

Based on this output, what city gas mileage would you predict for this car? _[pred]_ Round answer to the nearest hundredth (2 decimal palces).
