The key to setting up an addition expression of this nature is to carefully read the problems several times. Read it once in entirely to get an idea of the complete situation and circle each number you read, that will help you see them and not overlook one number. Next carefully begin to construct your expression in the same order as presented in the problem. A common mistake in a problem like this one is forgetting the negative signs when the price dropped. A third reading of the problem to ensure the proper signs are in place is always a good measure.
