Suppose that people consume only three goods golf balls club
Suppose that people consume only three goods: golf balls, clubs and Gatorade.
2016 : Price of golf balls : $2 Quantity: 100, Price Clubs: $200, Quantity:10, Gatorade Price:$1, Quantity 200.
2017 : Price of golf balls : $3 Quantity: 150, Price Clubs: $250, Quantity:20, Gatorade Price:$2, Quantity 250.
Use fixed basket of goods : 100 balls, 10 clubs, 100 Gatorades. Base year is 2016.
Calculate percentage change of each of the three goods. What is the percentage change in the overall price level (inflation rate).
Do golf clubs become more or less expensive relative to Gatorade?
Does the well being of some people change relative to the well-being of others?
Explain in detail and show all calculations in detail.

% Change in Price of golf ball = ((2-2)/2)*100 = 0
% Change in Price of golf clubs = ((125-200)/200)*100 = -37.5 percent
% Change in Price of gatorade = ((1.6-1)/1)*100 = 60 percent
Price level of 2016 = 2*100+200*10+1*200 = 2400
Price level of 2017 = 2*100+125*10+1.6*200 = 1770
Overal price level = ((1770-2400)/2400)*100 = -26.25 percent
Golf clubs are less expensive relative to Gatorade as the price of clubs decreased by 37 percent whereas the price of Gatorade increased by 60 percent.
True as the people who buy Gatorade are worse off than people who buy golf balls and golf clubs
