3. Assume that a grower of flower bulbs sells its annual output of bulbs to an Internet retailer for $70,000. The retailer, in turn, brings in $160,000 from selling the bulbs directly to final customers.
What amount would these two transactions add to personal consumption expenditures and thus to GDP during the year?
4. Suppose that in 1984 the total output in a single-good economy was 7,000 buckets of chicken and that the price of each bucket of chicken was $10. In 2005 the price per bucket of chicken was $16 and 22,000 buckets were produced.
Determine the GDP price index for 1984, using 2005 as the base year.
Instruction: Enter your response as an index number rounded to one decimal place.

8. Suppose that Glitter Gulch, a gold mining firm, increased its sales revenues on newly mined gold from $75 million to $150 million between one year and the next. Assuming that the price of gold increased by 100 percent over the same period, by what numerical amount did Glitter Gulch's real output change?
If the price of gold had not changed, what would have been the change in Glitter Gulch's real output?
$ million
9. A mathematical approximation called the rule of 70 tells us that the number of years that it will take something that is growing to double in size is approximately equal to the number 70 divided by its percentage rate of growth. Thus, if Mexico's real GDP per person is growing at
7 percent per year, it will take about 10 years (= 70 7) to double.
Apply the rule of 70 to solve the following problem. Real GDP per person in Mexico in 2005 was about $11,000 per person, while it was about $44,000 per person in the United States. If real GDP per person in Mexico grows at the rate of 2 percent per year, how long will it take Mexico's real GDP per person to reach the level that the United States was at in 2005? (Hint: How many times would Mexico's 2005 real GDP per person have to double to reach the United States' 2005 real GDP per person?)
