Basic Question 0 of 5

The following model was fitted to a sample of supermarkets to explain profit levels:

Y-hatt = 132.3 + 0.031 X1t + 0.089 X2t + et

where
Y-hatt = profits in thousands of dollars
X1t = food sales in tens of thousands of dollars.
X2t = nonfood sales in tens of thousands of dollar.

For a $30,000 increase in food sales, by how much would the predicted value of the dependent variable change?
