The table shows the approximate number of tourists in two areas of the world during a recent year and the average rates of change in tourism. Destination Number of Tourists South America and the Caribbean Average Rates of Change in Tourists (millions per year) increase of 0.8 40.3 million Middle East 17.0 million increase of 1.8 a. Define the variables, and write an equation for each region's tourism rate. b. If the trends continue, in how many years would you expect the number of tourists in the regions to be equal?

Answer 1

Given data:

The given table shown.

Assume x is the nummber of years, the expression for the south american and caribean tourist rate is,

y=0.8x+40.3

The expression for the Middle Eastt tourism rate is,

y=1.8x+17

Thus, the first expressionn is y=0.8x+40.3, and second expression is y=1.8x+17.
