PLEASE HELP QUICK!! The price of fuel may increase due to demand and decrease due to overproduction. Marco is studying the change in the price of two types of fuel, A and B, over time.

The price f(x), in dollars, of fuel A after x months is represented by the function below:

f(x) = 2.15(0.98)x

Part A: Is the price of fuel A increasing or decreasing and by what percentage per month? Justify your answer. (5 points)

Part B: The table below shows the price g(m), in dollars, of fuel B after m months:

m (number of months)1234

g(m) (price in dollars)4.193.983.783.59

Which type of fuel recorded a greater percentage change in price over the previous month? Justify your answer. (5 points)

Don’t you have to flip the sign when you divide by a negative? So I think she’s wrong bc the answer should be d is less than or equal to 7.5

Please refer to the answer below 🙂
