Architecture Word Problem

A new hotel/casino/resort is being built. It's total height is 1000 feet above sea level, plus 50 ft for each story.
                                                   
equation:    y=1000+50x

What would the height be if 60 stories are built?
equation: y=1,000+50(60)
               y= 1,000+3,000
               y= 4,000
If 60 stories were built, the height would be 4,000 ft.
