Answer:
45.1
Step-by-step explanation:
The original amount is 82
But the wrong amount is 45
So we will have to calculate the percentage for the error
82-45
37
So %error= 37/82 ×100
=3700/82
=45.121~45.1( to nearest tenth)
So the final answer is 45.1%
For downstairs- 28 x 38= 1064
For upstairs- 26 x 14= 364
All together- 1064 + 364= 1428
So.... 1428 seats in total.
Hope this helped! :)
