Answer:
Breyana paid 88% of the dress's original price.
Step-by-step explanation:
We are given the following in the question:
Let x be the original price of dress.
The dress is on sale for 20%.
Price of dress after discount =
Breyana will also have to pay 10% sales tax on the discounted price of the dress.
Price of dress after discount =
Total cost of dress =
We have to calculate percentage of original price paid by Breyana
Thus, Breyana paid 88% of the dress's original price.

How to find the value of the expression?</h3>
Here we have the expression:
3 + 2*(8 - 5) + 6
We start by solving the parenthesis, 8 - 5 = 3, then we get:
3 + 2*3 + 6
Now we solve the product: 2*3 = 6, then we get:
3 + 6 + 6
Now we can directly solve that addition:
3 + 6 + 6 = 3 + 12 = 15
We conclude that the expression is equal to 15.

Answer:
The smallest amount is £6911
Step-by-step explanation:
Rate of Interest = R = 5% per year
Duration in years = n = 3 year
Amount expected after three years when compounded annually = A = £8000
Formula for Amount of compound interest annually is a follows
A = P( 1 + R/100)^n
In our case Principal P = x , Amount A = 8000 , R = 5% and n = 3( since compounded annually). On substituting these values in above formula we get
8000 = x ( 1 + 5/100)^3
⇒8000 = x ( 105/100)^3
⇒8000 = x ( 21/20 )^3
⇒(8000 × 20 × 20 × 20)/(21×21×21) = x
⇒x = 6910.70≈6911
