Q$)$Consider A small Sub assembly

Set up time $=3$ hours per assembly Run$/$Build time $($one unit$)=150$ hours Maximum workers per shift per tool $=2$ people Working hours per shift $=7\mathrm{.}75$ hours Maximum shifts per day $=3$ shifts Round figures to nearest $0\mathrm{.}1$

$1)$To produce one assembled part every $7$ days how many shifts are required if you have one tool and one assembler per shift $?$

$2)$ What is the number of days required to produce one assembly if you have two assemblers on one shift only $?$

$3)$ What is the number of days required to produce one assembly If you have three assemblers total, using two shifts $?$

$4)$ To produce an assembly every $5$ days, how many shifts are required using the maximum number of workers, utilizing one tool?
