The price of washing machine was decreased by 21% and then by 55 € due small sales. After two price decreases cost € 343.
How much was originally cost?

Correct result:

x =  503.8 Eur

#### Solution:

$q = 1 - \dfrac{ 21}{100} = 0.79 \ \\ x = \dfrac{ 343 + 55}{ q } = \dfrac{ 343 + 55}{ 0.79 } = 503.8 \ \text{Eur}$
