PLEASE HELP ASAP Situation The context you find yourself in is Electronics store owner. The name of your store is Electro Hut As an owner you want to make a profit. You need to price the products you are selling, but need to make sure that overall you have 30% profit but two of the products you sell require you to sell them for a price set by the manufacturer • The challenge involves dealing with your customers. In order to be the best store in town you must not over charge. Adding 30% to all the items except the products that you must sell at a price set by the manufacturer will ensure you dont price too high . For the two items that prices are set by the manufacturer you need to find the amount of profit that manufacturer is allowing you to make Finally, you will need to write a summary paragraph which needs to explain what you did and why you did it

Submarines control how much they float or sink in the ocean by changing the volume of air and water contained in large ballast tanks. when the tanks are completely full of water, the submarine increases its overall mass and sinks down to the bottom. when the tanks are completely full of air, the submarine reduces its overall mass and floats to the surface. depending on the density of the seawater surrounding the submarine, it will pump seawater in or out of the tanks in order to achieve the same overall density as the sea water and float neutrally in the water. the volume of the submarine never changes. when the tanks are completely full of water, a submarine with a volume of 7.8\times10^3\text{ m}^37.8×10 3 m 3 7, point, 8, times, 10, start superscript, 3, end superscript, space, m, start superscript, 3, end superscript has a total mass of 8\times10^6\text{ kg}8×10 6 kg8, times, 10, start superscript, 6, end superscript, space, k, g. the density of the seawater is 10^3\text{ kg/m}^310 3 kg/m 3 10, start superscript, 3, end superscript, space, k, g, slash, m, start superscript, 3, end superscript. to make that submarine float neutrally, and neither float nor sink in the ocean, what volume of water does that submarine need to subtract from its tanks?
