Hi there
Total cost of job=
Retail price of goods+labor cost+OH
First find the labor cost
Labor cost=worker A+worker B+worker C
Worker A=13×1.5=19.5
Worker b=9.5×(1+3÷4)=16.63
Worker C=5×(2+3÷4)=13.75
Total labor cost
=19.5+16.63+13.75=49.88
Overhead cost49.88×0.75=37.41
Total cost of job is
74.5+49.88+37.41=161.79
So it's option d
Hope it helps
