Question 2: How large will Canada's GDP be in 25 years? The answer depends on what the rate of growth in GDP will be over that 25-year period. A mathematical formula we can use for this calculation is the following: GDP 2043 = GDP201a (1 + g) where GDP2043 is the level of GDP in the year 2043, GDP: is the level of GDP in the year 2018, and g is the rate of growth in GDP. a. Assume that GDP in 2018 is $1000 million and assume that the value of g is 0.035 (3.5 percent per year). What will be the value of GDP in 2043
