Question 897962: Okay, so I am doing my algebra homework, and my teacher was gone today so he wasn't here to explain what we do. Could you possibly help me solve this:
"Your car holds 16 gallons of gas. What would be the reasonable domain and range for the cost to fill up your tank if gas costs $3 per gallon?"
It'd be very much appreciated if you help! I would have tried to solve it, but I don't even know where to begin. Please and thank you very much!
