1. As the owner of an ice-cream store, you believe it is necessary to purchase another ice-cream maker to meet the increased demand. You need to take a loan to finance it. The loan officer tells you that your revenues of $750,000 are insufficient to support additional debt. To qualify for the loan, your revenues need to be $50,000 higher. To generate additional revenue, you collect data on the price (in cents) per pound you charge customers and the related quantity of ice-cream consumed per year in pounds. The information is saved in HW3_2.xlsx. Use these data to estimate the log-linear demand specification to obtain least squares estimated of the demand for ice-cream. Write an equation that summarizes the demand for ice cream, and then determine the percentage price increase or decrease that is needed in order to boost revenues by $50,000.
