olasank [31]
Given that <span>work hours in new zombie are 200 in year 1 and productivity is $8 per hour worked.

The new zombie's real gdp in year 1 is given by 200 x $8 = $1,600

If work hours increase to 210 in year 2 and productivity rises to $10 per hour.

The new zombie's real gdp in year 2 is given by 210 x $10 = $2,100

The new zombie's rate of economic growth is given by

\frac{\$2,100-\$1,600}{\$1,600} \times 100\%= \frac{\$500}{\$1,600} \times100\%=31.25\%</span>
