Question

A shop owner

allowed a discount of
of 10% on a pice of an item if the new price of the item is 90$ find the original price

Answer 1

$100

Explanation:

$90 is the price after a 10% discount, which can be understood as $90 is 90% of the original price. Therefore we can set up the equation

90=.9x (x is the original price)
Divide by .9 on both sides to solve for x
x=100

Answer 2

100 dollars is the original price

Explanation:

90 dollars = 0.9x

divide by 0.9 each side to get x

100 dollars = x

x = original price
