A regression has yielded the following results on movie box office, production budget, and star power:

Box Office $=1+0\mathrm{.}2*$ Budget $+50*$ Star Power

Where both "Box Office" and "Budget" are measured in million dollars, and "Star Power" is a variable between $0$ and $1,$ measuring the star power of the leading actor or actress $(0=$ Unknow actor$/$actress$,1=$ Super Star, and a number between $0$ and $1$ reflects how well known the leading actor$/$actress is$).$

Answer the following question based on the regression results.

If a movie increases the budget by $1$ million dollars, everything else equal, how much do we expect the box office to increase?
