Question

A clothing store is having a 20% off sale. Phoebe has a coupon that will give her 10% off the already discounted price. How much will she pay for a dress that originally costs $52?

Answer 1

$37.44

Step-by-step explanation:

The original cost of the dress = $52

The clothing store is having a 20% off sale, thus:

`\begin{gathered} \text{The discounted price=}52-(20\%\text{ of 52)} \\ \text{=}52-(0.2*52) \\ =52-10.4 \\ =\$41.6 \end{gathered}`

Phoebe's coupon will give her 10% off the already discounted price.

Thus, the amount she will pay for the dress:

`\begin{gathered} =41.6-(10\%\text{ of 41.6)} \\ \text{=41.6}-(0.1*41.6) \\ =41.6-4.16 \\ =\$37.44 \end{gathered}`

Phoebe will pay $37.44.
