Question

Find the discounted price of each item.

MP3 player: $\mathrm{\$}69.00$, discount: $20\%$.

Short answer

The discounted price of the items is$\mathrm{\$}55.2$

Step-by-step solution

Step 1. Given information.

We have ‘MP3 players:$\mathrm{\$}69.00$,discount: $20\%$.

To find the discounted price of the items.

Step 2. Apply concept.

Firstly, we find the tax amount of the cost of the items then find the discounted price of the items by this formula.

$\text{Discountedpriceoftheitems}=\mathrm{Pr}\text{iceoftheitems}-\text{discountamountoftheitems}$

Step 3. Calculation.

The discount amount of the items is:

$\begin{array}{c}20\%\text{\hspace{0.17em}of69=}\frac{20\times 69}{100}\\ =2\times 6.9\\ =\mathrm{\$}13.8\end{array}$

So, the discounted price of items is:

$\begin{array}{l}\text{costofitems-discountamount}\\ \text{=\$69-\$13.8}\\ \text{=\$55.2}\end{array}$

Hence, the discounted price is $\mathrm{\$}55.2$.
