For question 1, b)

How do I calculate the "Marginal Rock Utils per $" column. Can you please explain? Thank you.

Question 1 [18 points] David loves to go on Camping trips. Going on a Camping trip costs David a total of $46 per trip. David also loves to go to Rock concerts. Going to a concert costs David a total of $20 per concert. David must allocate his monthly entertainment budget carefully, and has evaluated how much satisfaction, measured in utils, he obtains from each Camping trip and each Rock concert visit. David's total utility from each activity is independent of the amount of the other activity he engages in. David has an entertainment budget of $290. Suppose that the price of a Rock concert falls to $15 from $20. The income budget remains at $290. Visits past 7 will not give any extra utility. a) Compute David's original equilibrium (before the price change). Original number of Camping trips = I Original number of Rock concerts = I b) Fill out the table for the new MU/P for Rock concerts (after the price change). Keep as much precision as possible during your calculations. Your nal answer should be accurate to at least two decimal places
