In the bathhouse, a bathtub that can be filled with water up to 10 liters (L) is filled with water for the guests. 3 guests used 1 liter (L) and 500 milliliters (㎖) of water from this bathtub, and 1 guest used 1 liter (L) and 750 milliliters (㎖) of water. If the remaining guests each use 1 liter (L) and 250 milliliters (㎖) of water, how many people can take shower?
