Sarah is a server at a restaurant and has been keeping track of the tips she receives.The smallest bill she received a tip for was $24.44,and the largest bill was $89.75.She used linear regression to model tips received (y)as a function of the restaurant bill (x).Using her data,she wrote a linear regression equation of y = 0.22x-0.27.Sarah would really like to get a $50 tip.Based on her linear regression equation,what would the restaurant bill have to be to lead to a $50 tip? Would this calculation be considered interpolation or extrapolation?

To get a tip of $50.00,the restaurant bill would have to be $228.50.Since $228.50 is not in the domain of the data Sarah collected,it would be considered extrapolation.
