Hi,<span>
Let x be 100 dollars(since per cent means out of 100)(also SP)
</span>SP without sales tax= 100 - d%/100 * SP
= 100-20/100 * 100
=80/100 * 100
= 0.8 * 100
= 80 dollars=SP without tax
tot. SP(SP with tax)= 100 + tax%/100 * SP
=100 + 10 /100 * 80
= 110/100 * 80
= 11/10 * 80
=1.1* 80
=88%
Breyanna will have to pay 88% <span>of the dress original price.
Hope this helps you.</span>

Answer:
The area of the roof is 3.80 m².
Step-by-step explanation:
The lateral surface area of an octagonal pyramid is given by:
(1)
Where:
s: is the length of the base edge = 0.5 m
h: is the height
We can find the height from the slant height (S = 1.9 m):
(2)
By solving equation (2) for "h" we have:

Now, we can calculate the area of the roof (equation 1):
Therefore, the area of the roof is 3.80 m².
I hope it helps you!
