Hey there!!
Let's take a closer look at the question,
We have the original price with included 15% tax
This original price is first reduced by 35% , first let's solve this.
35% = 35 / 100 = 0.35
0.35 × 1899
... $664.65 = 35% of of $1899.00
It would be sold for
... 1899 - 664.65
... $1234.35
Now, this price is further reduced by 20%
20% = 20/100 = 0.20
... 0.20 × 1234.35
... $246.87
This is 20% of 1234.35
Now, the price it would be sold for =
... $1234.35 - $246.87
... $987.42 is the final price the sofa would be sold for.
Hope my answer helps!!
