=+2 Jones Ltd’s cost analyst uses annual data from past years to estimate the following regression equation with total manufacturing costs of the bicycle frame as the dependent variable and bicycle frames produced as the independent variable:

y = $435 000 + $19X During the years used to estimate the regression equation, the production of bicycle frames varied from 31000 to 35000. Using this equation, estimate how much it would cost Jones Ltd to manufacture 35000 bicycle frames. How much more or less costly is it to manufacture the frames rather than to acquire them from Ryan Ltd?
