So here we need to think about what gdp and gdi are.
00:04
So for the first start, gdp is as is very commonly done, given as c plus i plus g plus nx, right? and so we know that we know that gdp is $14 ,991 billion.
00:19
We know that consumption is 10, 729.
00:23
We know what invest, we don't know what investment is, right? this is just a, is a mystery, but we're going to get it.
00:30
We know that government spending is 2594, and we know that net exports are minus 568, right? so we can simply rewrite this equation by bringing those terms to the other side and solving for i.
00:46
And when we do this, we get that i is equal to 2236, right? it's the number that balances the equation.
00:51
This is what's important, right? so for b, we have gdi, which is the exact same thing, and gdi is just a number...
