Question

g m = - 0.05 m + 12.1 The given function g models the number of gallons of gasoline that remains from a full gas tank in a car after driving m miles. According to the model, about how many gallons of gasoline are used to drive each mile?

Accepted Answer

Choice A is correct. It's given that the function g models the number of gallons that remain from a full gas tank in a car after driving m miles. In the given function g m = - 0.05 m + 12.1 , the coefficient of m is - 0.05 . This means that for every increase in the value of m by 1 , the value of g m decreases by 0.05 . It follows that for each mile driven, there is a decrease of 0.05 gallons of gasoline. Therefore, 0.05 gallons of gasoline are used to drive each mile. Choice B is incorrect and represents the number of gallons of gasoline in a full gas tank. Choice C is incorrect and may result from conceptual errors. Choice D is incorrect and may result from conceptual errors.
