Question 740343
the price of a puzzle was cut 20% for a trade fair event.
By what percentage must the puzzle item be increased again to sell it at the original price?
:
Let p = original price
Let x = percentage required to return to the original price
:
p - .2p = .8p
:
.8p*x = p
Divide both sides by p
.8x = 1
x = 1/.8
x = 1.25
Price has to be increased by 25%
