From the second table, we can see that the regression equation is y = 73.72 + 14.22x1 - 8.35x2 - 48.67x3 Plug in x1 = 10, x2 = 0, and x3 = 0 (since they are not given in the question), we get y = 73.72 + 14.22(10) - 8.35(0) - 48.67(0) = 1,928.24 Therefore, the predicted value of y is 1,928.24 when x₁= 10.
