Your next order of business is doing an inspection of the kitchen and cleaning area of Top O' the Morning, a trendy Irish eatery. The proprietor, Sean McWiggy, has been running the restaurant for only eight months, so there might be a few problems.

It takes only a few minutes for you to inspect the kitchen and cleaning area. Here is what the inspection checklist looks like:

OFFENCEDEMERITS
Dishes piled up on potato sack on floor2.5
Fly swatter left on chopping block5.0
Windows wide open (allowing flies and mosquitoes in)2.5
Sack of onions on dirty floor in back2.5
Can of fly spray on chopping block1.5
Flies eating pre-made side-dishes7.0
Pre-cut french fries warm and soggy3.5

"Math is always there in my work," says health inspector Jacques Oullet. "Anyone who's being inspected is being inspected on a real or implied marking system. A person with three health violations is doing better than a person with 10. The difference is always mathematical. Health inspectors are not mathematicians, but they do have to have some familiarity with it."

You're working with a 100-point system. A pass is 75 or more points. McWiggy started with 100 points and cannot lose more than 25 points if he is to pass. Did he? Pass, that is. If so, by how much? If not, by how much?
