In$-$class activity $2$

$1-$ Find the number of component we need to start with $($I$1).$

$2-$ If the pressing process takes $\backslash (12\backslash$mathrm$\{$mins$\}/\backslash )$ board. Out of the $\backslash (2,000\backslash$mathrm$\{$hrs$\}\backslash )$ available per year, the pressing machine will be operational $\backslash (90\backslash \%\backslash )$ of the time. During the time the machine is operational, parts are produced at a rate equal to $\backslash (95\backslash \%\backslash )$ of the standard rate. How many pressing machines are needed?
