I am performing a $3$ wire level and my top wire reading on the backsight is $4\mathrm{.}56.$ If my actual distance from the backsight was $152\mathrm{.}5\text{'},$ what should my reading be on the bottom wire if the stadia factor for the level is $100?$

$3\mathrm{.}04$

$6\mathrm{.}08$

$4\mathrm{.}24$

$3\mathrm{.}18$
