below the question- i just copied and pasted. the attached pictures is what i have so far already, i wanted to see if you can check and see if there any errors i should know of and the teacher asked me to label the answers in yellow highlight- i think i know where but i wanted to make sure i was right, can you point out?I basically wanted to make sure i not missing out anything

two points on the demand curve were given. Suppose three additional points are estimated by Madison: (1) demand of 460 when price is $65, (2) demand of 355 when price is $75, and (3) demand of 275 when price is 85.

a) With these new points and the original two points, estimate the best-fitting linear demand curve; do the same for the best-fitting constant elasticity demand curve.

b) Suppose we decide to use the constant elasticity demand curve for prediction. What price will Madison charge to maximize the total profit?Please include both the model worksheet and the answer report in your excel file.
