Chapter 1, Problem 14PE

Automobiles have different fuel economies (mpg), and commuters drive different distance to work or school. Suppose that a state Department of Transportation (DOT) is insterested in measuring the average monthly fuel consumption of commuters in a certain city. The DOT might sample a group of commuters and collect information on the number of miles driven per day, number of driving days per month, and the fuel economy of their cars. Develop a predictive model for calculating the amount of gasoline consumed, using the following symbols for the data. G   =   g a l l o n s   o f   f u e l   c o n s u m e d   p e r   m o n t h m   =   m i l e s   d r i v e n   p e r   d a y   t o   a n d   f r o m   w o r k   o r   s c h o o l d   =   n u m b e r   o f   d r i v i n g   d a y s   p e r   m o n t h f   =   f u e l   e c o n o m y   i n   m i l e s   p e r   g a l l o n Suppose that a commuter drives 30 miles round trip to work 20 days each month and achieves a fuel economy of 34 mpg.
