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 manufacture. 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 manufacture will ensure you don't price too high.

For the two items that prices are set by the manufacture you need to find the amount of profit that manufacturer are allowing you to make.
