as part of a weight reduction program, a man designs a monthly exercise program consisting of bicycling, jogging, and swimming. he would like to exercise at most 20 hours, devote at most 9 hours to swimming, and jog for no more than the total number of hours bicycling and swimming. the calories burned by this person per hour by bicycling, jogging, and swimming are 200, 639, and 261, respectively. how many hours should be allotted to each activity to maximize the number of calories burned? what is the maximum number of calories he will burn? (hint: write the constraint involving jogging in the form ≤0.)
let x 1 be the number of hours spent bicycling, let x 2 be the number of hours spent jogging, and let x 3 be the number of hours spent swimming. what is the objectivefunction?
