Marina paid $2,000 for a tablet PC after receiving a 25 percent discount. What was the price of the tablet before the discount?
tensa zangetsu [6.8K]

The price of the tablet before the discount is $ 2667

<h3><u>Solution:</u></h3>

Given that Marina paid $2,000 for a tablet PC after receiving a 25 percent discount

To find: The price of the tablet before the discount

Let "a" be the price of the tablet before the discount or original price

After receiving a 25 percent discount means 25 percent discount in original price

Discount = 25 % of original price

Discount = 25 % of "a"

\begin{array}{l}{\text {discount}=\frac{25}{100} \times a} \\\\ {\text {discount}=0.25 a}\end{array}

Now we can say that,

<em>price of tablet after discount = price of the tablet before the discount - discount</em>

2000 = a - 0.25a

0.75a = 2000

a = 2666.67 ≈ 2667

Thus the price of the tablet before the discount is $ 2667
