Petr would like to buy a new smartphone. If he starts a temporary job at the electro shop he gets payed $120\mathrm{CZK}$ per hour plus he gets $20\mathrm{\%}$ discount on the smartphone bough in the shop. He calculated that for $24$ hours of work he would not earn even half of the phone price. Another employer pays $150\mathrm{CZK}$ per hour. If Petr gets a temporary job with the other employer he is not eligible for the discount in the electro shop anymore, however he can buy the smartphone from e-shop for the price by $600\mathrm{CZK}$ lower than in the electro shop and for $20$ hours of work he earns more than one third of the electro shop smartphone price. Determine as closely as possible the smartphone price in the electronics shop.
