How would I use a logarithmic model (y = a + b ln x) for the information that is in the picture? X is the number of jackets so the 1000, 2000 3000 and so on and the Y can be either the price demand or the price supply.

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.

How many desks and whats the price?
