Since there are 8500 chairs
Since this number id decreases by 6%
Then to find 6% of 8500, multiply 6% by 8500
At first, change 6% to a normal number by dividing it by 100
6% = 6/100
[tex]\frac{6}{100}\times8500=6\times85=510[/tex]The amount of decreases in the number of chairs produced each month is 510
To find the new number of chairs subtract 510 from 8500
[tex]8500-510=7990[/tex]The new number of chairs produced each month is 7990
