solve this question

Suppose nominal GDP increased by 1.5 % . Over that year , the GDP deflator decreased by 0.5 % . From this information ( and using our Aggregate Supply and Demand framework for analysis ) , we infer that
a . real GDP increased , and we had an increase in Aggregate Demand .
b . real GDP increased , and we had a decrease in Aggregate Demand .
c . real GDP decreased , and we had an increase in Aggregate Supply .
d . real GDP increased , and we had an increase in Aggregate Supply .
e . real GDP decreased , and we had a decrease in Aggregate Demand .
Do #5 in Chapter 4. On this question, I want you to not only indicate your choice of ‘lettered answer,’ but also explain and illustrate how you arrived at your answer. In other words, treat it like a short answer question (illustrate with detailed graphs, show calculations, explain the details of what you are doing, etc.). Here’s an IMPORTANT point. Do NOT plug the percentage changes (‘1.5’ and ‘- 0.5’) into the formula for realGDP as the index numbers themselves. Percentage Changes are NOT index numbers. For instance, if X increases from 200 to 203, X has increased by 1.5%. You would NOT plug in ‘1.5’ as X! Use the % changes in nGDP And the GDP deflator to tell if the ‘fraction’ in the formula for realGDP has increased or decreased. If it helps as an analogy, think of the numerator (top of a fraction) as a ‘pot of money’ and the denominator (bottom of a fraction) as the ‘number of persons to share the pot of money equally.’ Then if you know the % change in each (and whether the particular % change is an increase or a decrease), then you should be able to tell if the fraction is increasing, decreasing or staying the same.
Below, I include some details on procedures…
When it’s time to do your assignment: Save your work as a pdf file and ‘attach it to the assignment.’ You can type your answers or write them by hand. (Do NOT do your work on the question sheet – there is not enough room for sufficient explanations of your answers.) In either case, you’ll need to show graphs and/or math work and give explanations as necessary for the questions. If you type your answers, you’ll need to do graphs with some sort of drawing program. If you don’t have access to (or facility with) such a program, you can write your answer by hand. If you have access to a scanner, you can scan your work and save it as a pdf file. If you type and use a drawing and math typing program, you should be able to save your file as pdf. If neither of these work, you should be able to take a cell phone photo, email it to yourself, download it and then save it as a pdf file. You should be able to google steps if you still are unsure how to do save things as a pdf file. * Then you’ll need to upload the file to this ‘assignment.’
