Show me the steps to solve: A rm$\text{'}$s production function is f $($x$1$ ; x$2)=($minfx$1$; $5$x$2$g$)1=2.$ If the price of factor $1$ is w$1=4$ per unit and the price of factor $2$ is w$2=15$ per unit, then its supply function is given by the equation S$($p$)=($a$)$ p$=14.($b$)$ p$($maxfw$1$; $5$w$2$g$).($c$)$ p$($minfw$1$; $5$w$2$g$).($d$)7$p$.($e$)$ pminf$4$p; $75$pg$.$
