Question

The average width of a movie theater seat is 23 inches. Thirty years ago, the typical movie theater seat was approximately 19 inches wide. Current movie theater seats are what percent of a theater seat from 30 years ago?

Answer 1

To solve the problem, we can use the formula for finding percent increase:

percent increase = [(new value - old value) / old value] x 100%

Let's substitute the given values into the formula:

percent increase = [(23 - 19) / 19] x 100%
percent increase = 4/19 x 100%
percent increase = 21.05%

Therefore, current movie theater seats are approximately 21.05% wider than theater seats from 30 years ago.
