You have a log utility, U=ln(W), where W is your wealth. Currently, you own $1,000. You are given the chance to receive a payment of $627 with a probability of 67%. Given the Expected Utility Theory, how much certainty payment would make you indifferent between taking a chance and taking the certainty payment? Enter a number with two decimal points. Answer the question in dollar amount, i.e., if the answer is $20, enter 20.00 . (Note: whenever the calculation involves log and exponential operations, it is wise to keep more decimals in your intermediary steps so that your final two-decimal answer is accurate.)
