Suppose that the British economy produces two goods: laptops and books. The quantity produced and the prices of these items for 2015 and 2016 are shown in the table below:
Year | Quantities produced | Price ($) |
2015 | Laptops = 50 Books = 1,000 |
Laptops = 250 Books = ? |
2016 | Laptops = 90 Books = ? |
Laptops = 150 Books = 10 |
Instructions: Round your answer to two decimal
places.
a. Let’s assume that the base year was 2015, so that real GDP in 2015 equals nominal GDP in 2015.
If the real GDP in Britain was $20,000 in 2015, the price of books was
.
Instructions: Round your answer to the nearest whole number.
b. Using your answer from part (a), if the growth rate in nominal GDP was 10 percent, books must have been produced in 2016.
Instructions: Round your answer to one decimal place.
c. Using your answers from parts (a) and (b), the growth rate in real GDP between 2015 and 2016 was

Nominal GDP in 2015 is the (price of laptops in 2015 times quantity of laptops in 2015) + (price of books in 2015 times quantity of books in 2015) | ||||||||||||
Nominal GDP in 2015 is $22,000 | ||||||||||||
a) $7.50 | ||||||||||||
(250*50) +(X *1000) = 22000 | ||||||||||||
