A foreign tourist went shopping in a shop in Hungary with only euros. Luckily for him, the shop accepted euros. At the end of the bill was the following:
Amount to pay: 2440 Ft (this is the amount of money you have to pay)
Paid: 10 euros (the amount he gave the cashier)
How many forints did you get back if the shop exchanged the euro at the exchange rate of 1 euro = 305 forints?
