Real-Life Math
Laser printer repair technicians pride themselves on being able
to fix even the quirkiest of office machines. And before they leave, they
also write up a bill.
While some companies have service plans that
pay in advance for service calls, others pay as they go. That means the technicians
must be able to figure out the charges before they head back out on the road.
You
are a technician who has just completed a morning's worth of work at
a local office. You fixed 3 printers, all with different problems:
Printer
1: Replace optical eye, clean, replace toner cartridge. Time: 45 minutes
Printer
2: Remove severely jammed paper and replace paper in-feed bin. Time: 30 minutes
Printer
3: Replace network cable wire (5 meters in length), replace toner cartridge.
Time: 75 minutes
You'll need to know the cost of
parts:
Optical eye: $150
Toner cartridges: $75 each
Paper
in-feed bin: $95
Cable wire: $15 per meter
Then there
is the labor cost. Your company charges $70 per hour for your time. Finally,
you'll need to add on a 5 percent tax.
What will
the final cost of this morning's work be?
