Accountants at the Tucson firm, Larry Youdelman, CPAs, believed that several traveling executives were submitting unusually high travel vouchers when they returned from business trips. First, they took a sample of 200 vouchers submitted from the past year. Then they developed the following multiple-regression equation relating expected trave cost to number of days on the road (x1) and distance traveled (x2) in miles: y^=$95.00+$48.50x1+$0.40x2. The coefficient of correlation for the model is 0.72. a) If Donna Battista returns from a 320-mile trip that took her out of town for 4 days, the expected amount that she should claim as expense =$ (round your response to two decimal places)
