Inverse variation means y=k/x (direct variation is y=kx) so we can use the info given to find the constant k
y=k/x
6=k/900
k=6(900)
k=5400 so the equation is:
y=5400/x or more accurately for this problem
t(v)=5400/v then:
t(800)=5400/800
t(800)=6.75 hours
The answer is:
545>322
540 <997
Total cost job=
Retail price of parts+labor cost+manufacturing overhead
Total cost job 82
Retail price of parts 0
Labor cost=7.5×6.5=48.75
Manufacturing overhead ?
82=0+48.75+?
?=82−48.75
?=33.25
Manufacturing overhead is 33.25
Now find manufacturing overhead rate from the cost of labor
33.25÷48.75=0.682×100=68.2%
The answer 68.2%
