$(24)$ d$)$ Unfortunately, a strong earthquake $(5\mathrm{.}9$ on the Richter scale$)$ destroyed $25\%$ of Arcadia's capital. However, thanks to the very strict construction laws in the country, the population was not harmed, and the labour force remained unchanged at $200.($Assume again that $a=0\mathrm{.}2,b=0\mathrm{.}8).$

$($i$)$ What is the new total output level in Arcadia? By how much has it changed? Calculate. $($Round off to the nearest whole number.$)$

Explain the change in words $($i$.$e$.,$ is it higher or lower than the initial value, and why?$).$ Draw a graph of the production function with $K$ on the horizontal axis to illustrate the change. Show your work.
