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 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.

Finally, you will need to write a summary paragraph which needs to explain what you did and why you did it.

Try to find the number of flexable priced products you may sell. for 30% to the profit, you must factor in the total available numbers, and evenly divide the percentage lost to the other products. take 30% of the price you pay for the two regulated products, add that number and you may then divide that amount equaly to the already 30% profit you have factored in with the other items.

a- amount

B- price

p- necessary profit

c- profit per item

(Ba x.03) = p

p/(a-2) = c

((2.00 x 4) .30) =

=8.00 x .3

=2.4

4-2/ 2.4

2/ 2.4

1.2 = c

c should be how much you add to two items, and your done! you have a correct price set for your item that allow you to make 30% profit on all items excluding the two that must be kept at a standard price.
