a. Doubling time is given by the formula 70 / r
Doubling time for Belgium = 70 / 1.9 = 36.8 years. = ~ 37 years
Doubling time for Malaysia = 70 / 3.8 = 18 years
b. Per capita GDP was $22,000 in Belgium and $11,000 in Malaysia.
Exponential Growth = a ( 1 + r ) x . a is the per capita real GDP. r is the annual growth rate and x is the number of years which is 2034 - 1997 = 37 years
For Belgium: $22,000 ( 1 + 0.019 ) 37 = $22,000 * 2.006526 = $44143.57
For Malaysia: $11,000 ( 1 + 0.038 ) 37 = $11,000 * 3.974679 = $43721.47
c. It takes 38 years ( 2035 - 1997) for per capita real GDP in Malaysia to catch up with that of Belgium.
Cause in 2034, the GDP is almost close. And if one were to see the figures for 2035 for Belgium where
$44143.57 (1.019 ) = $44982.3
While Malaysia Real GDP per capita is $43721.47 * ( 1.038) = $45382.89
Malaysia's per capita real GDP is more than that of Belgium in 2035.
