Concept explainers
Tourism in the 1990s Referring to the 1998 tourism figures given in Exercise 51, assume that the following (fictitious) figures represent the corresponding numbers from 1988:
To | Australia | South Africa |
From North America | 500 | 100 |
Europe | 900 | 800 |
Asia | 1,400 | 50 |
Take A to be the
a. Compute the matrix
b. Assuming that the changes in tourism over 1988–1998 are repeated in 1998–2008, give a formula (in terms of A and B) that predicts the number of visitors from the three regions to Australia and South Africa in 2008.
