Let's pretend the USA’s Real GDP in 2015 was $6.2 trillion. If C = $2.5 trillion, I = $1.5 trillion, G = $1 trillion, then X = ,

which means are greater than .

Now, let’s pretend the USA’s Real GDP in 2016 was $7.5 trillion. If C = $3.6 trillion,

I = $2.1 trillion, and G = $ 2 trillion, then X = , which means

are greater than .

What was the growth in the USA’s Real GDP from 2015 to 2016? Did the USA achieve its goal for GDP growth (which is the same as the US), and how do you know?

Dr. sperry, a biologist, is using excel to track growth rates of different populations of bacteria. she has a very complex formula in one cell. it begins with “round”. dr. sperry would like to see exactly how excel’s calculation reached the final rounded value that she sees in the cell. what could dr. sperry do to best understand how the calculation was made? try different formulas on her own until she reaches the value shown in excel click on the evaluate formula button in the formulas tab and then click “step in” select the cell and then look at the formula in the formula field of the ribbon remove “round” from the formula in order to see the actual value before rounding
