2. Suppose you spend $25 on a meal and that you are then charged 6% tax and then you apply a 15% tip on top of that. What is the total amount that you pay? Write a model, f(m), for the total with tax (that is, the cost of the meal plus tax) if the meal is originally $m and the tax rate is 6%. f(m) = Now write a model, g(m), for the total with tax and tip included if the meal is originally $m, the tax rate is 6%, and the tip is 15%. g(m) = Find g(25) and compare to your answer above. g(25) =
