Acustomer calls to ask how often he should change the oil in a lawn mower engine. after asking the customer for the manufacturer's name and the model number of the lawn mower engine, you check the service manual for the engine. the engine manufacturer recommends that you change the oil after every 50 hours of light- or normal-duty operation, or after every 25 hours of heavy-duty operation. the customer tells you that he is the groundskeeper at a local golf resort. he uses this mower only to trim the greens on the course. he mows the greens 2 times per week; each time, it takes a total of 5 hours to complete the job. the golf course is open 30 weeks out of the year. if you consider the mowing of the golf course to be normal-duty operation, how often should you tell the customer to change the oil in the mower engine? (hint: you'll need to calculate the total number of hours the groundskeeper uses the mower per year. assume that it's now the beginning of the 30-week golf resort season.)
a. the oil should be changed a total of 2 times during the 30-week season.
b. the oil should be changed a total of 3 times during the 30-week season.
c. the oil should be changed a total of 6 times during the 30-week season.
d. the oil should be changed a total of 10 times during the 30-week season.
