Question

Find the original price of a pair of shoes if the sale price is $84 after a 30% discount.

Answer 1

Answer:

Original price = $ 120

Step-by-step explanation:

To find the original price given the new price and percentage discount we use the formula

$original \: \: price = \frac{100}{(100 - x)} \times new \: \: price$

where

x is the percentage discount

From the question

new price = $ 84

% discount = 30%

Substitute the values into the above formula and solve

That's

$original \: \: price = \frac{100}{100 - 30} \times 84 \\ = \frac{100}{70} \times 84 \\ = \frac{10}{7} \times 84 \\ = 12 \times 10$

We have the final answer as

Original price = $ 120

Hope this helps you
