Breyana is buying a new dress. The dress is on sale for 20% off. Breyana will also have to pay 10% sales tax on the discounted p
Vinvika [58]

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 =

(x-0.20x)

Breyana will also have to pay 10% sales tax on the discounted price of the dress.

Price of dress after discount =

0.10(x-0.20x)

Total cost of dress =

(x-0.20x) + 0.10(x-0.20x)

We have to calculate percentage of original price paid by Breyana

\dfrac{(x-0.20x) + 0.10(x-0.20x)}{x}\times 100\%\\\\=\dfrac{0.80x+0.08x}{x}\times 100\%\\\\=\dfrac{0.88x}{x}\times 100\%\\\\=88\%

Thus, Breyana paid 88% of the dress's original price.

A company sold garden hoses at a reduced price of $6.67 and took an end-of-season mark down of $9.28. What was the original sell
saul85 [17]

We have the formula:

M=S-N

where M is the mark down, S is the original price and N is the reduced price. Plugging the values we know:

\begin{gathered} 9.28=S-6.67 \\ S=9.28+6.67 \\ S=15.95 \end{gathered}

Therefore the original price was $15.95
