Please calculate the change in the forward price of the futures contract for EUR 10,000 taken at a

price of PLN 389 / EUR 100, which will cause a margin call, assuming that the initial deposit is 12% of the contract value, and the maintenance margin level is set at PLN 3500 (fixed amount). We take a long position. What will be the amount of the call?

*A task can also be done for a variable maintenance margin of 10%.
