A wholesaler purchased a product at a cost of 40 yuan/kg for a total of 700 kg. According to market forecasts, the selling price $y$ (yuan/kg) of the product is a function of the storage time $x$ (days), given by $y=50+2x$. However, storing this batch of products incurs a loss of 15 kg per day, and the products can be stored for a maximum of 15 days. Additionally, the daily storage cost for the wholesaler is 50 yuan.
(1) If the wholesaler sells the product in one go after storing it for 5 days, the profit will be     yuan.
(2) If the wholesaler wishes to make a profit of 10,000 yuan from selling this batch of products, how many days should the wholesaler store the product before selling it all at once?
