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 eight 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 32,000 miles. You change the oil filter every other time the oil is changed. The normal price for oil is $22.99 per case. Oil filters cost $4.99 each. What is the total yearly cost for all oil and oil filters?
