Suppose an economy has three sectors: Mining, Services and Tourism. Mining sells 20% of its output to Services and (D + 35)% to Tourism, and retains the rest.
Services sells 32% of its output to Mining and (D + 10)% to Tourism, and retains
the rest. Tourism sells (D+25)% of its output to Mining and 35% to Services, and
retains the rest. Determine the exchange table for this economy, where the columns
describe how the output of each sector is exchanged among the three sectors. Also
write a linear system to represent income and expenditure. Do not solve the system.
