Step-by-step explanation:
1) First, before getting started, let's assume the price of the product is
. This variable will be used a lot throughout the problem (
).
2) Marking a price above means increasing the price in order to make money off of the purchased product. When raising something by
percent, the new price would be
.
---> In this case, the price increased by
percent.
This means that it would be: ![x+\frac{30}{100}x = x+0.3x=1.3x](https://tex.z-dn.net/?f=x%2B%5Cfrac%7B30%7D%7B100%7Dx%20%3D%20x%2B0.3x%3D1.3x)
New price is: ![1.3x](https://tex.z-dn.net/?f=1.3x)
3) The shopkeeper is then offering a
percent discount off of this marked price. When offering a
percent discount price, the new price (with discount), expressed algebraically is: ![a-\frac{b}{100}a](https://tex.z-dn.net/?f=a-%5Cfrac%7Bb%7D%7B100%7Da)
---> the expression above simplifies to ![(1-\frac{b}{100})a](https://tex.z-dn.net/?f=%281-%5Cfrac%7Bb%7D%7B100%7D%29a)
In this case,
, ![b=15](https://tex.z-dn.net/?f=b%3D15)
---> ![(1-\frac{15}{100})*1.3x = (1-0.15)*1.3x=0.85*1.3x=1.105x](https://tex.z-dn.net/?f=%281-%5Cfrac%7B15%7D%7B100%7D%29%2A1.3x%20%3D%20%281-0.15%29%2A1.3x%3D0.85%2A1.3x%3D1.105x)
This means that
, with discount, has been raised
.
10.5 % is the profit percent
(The profit percent being the final marked up price - purchased price)
