A fare meter in a taxi calculates the fare by starting at $2.40 when the trip starts, then adding $0.32 for every eighth of a mile traveled. If x represents the length of the trip in miles, what function models the total cost of the trip?

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
