Give an overview of proximity detectors.
What will be an ideal response?
Proximity detectors are designed to detect the presence or absence of some object. Some detectors are designed to detect metals only, and others have the ability to detect almost any material. Some rely on a change of inductance to detect the presence or absence of metal, and others rely on a change of capacitance to detect almost any object.

There is a special sale on engine oil. If you purchase more than one 12-quart case, you will receive a 5 percent discount. If you purchase six or more cases, you will receive a 10 percent discount. You have two vehicles that require an oil change every 4,000 miles. Vehicle #1 requires four quarts per oil change plus one additional quart when you also change the oil filter. Vehicle #2 requires five quarts per change plus one quart whenever the filter is changed. Each year your family drives vehicle #1 about 16,000 miles and vehicle #2 about 24,000 miles. You change the oil filter every other time the oil is changed. The normal price for oil is $22.49 per case. Oil filters cost $4.39 each. What will be the discount for a one-year supply of oil for both vehicles?
