Question

ou are purchasing a new car and want to know how the money spent on gas depends on the cars MPG. Determine whether the two variables are related in a way that might describe a function. If the situation is described as a function then identify the independent and dependent vatriables.

Answer 1

Total price of gas depends on three values: price per gallon, number of miles traveled, and MPG. Assuming none of these is constant, then we do have a function in which total price depends on MPG, but it also depends on two other variables. We have a multivariable function, with dependent variable total price and independent variables price per gallon, miles traveled, and MPG.
