Rise in price required = $50*50% - $15
Rise in price required= $10
Now let calculate How high can the price of the stock go
Price of stock=$50+$10
Price of stock= $60
Therefore How high can the price of the stock go before you get a margin call if the maintenance margin is 30% of the value of the short position is $60
