Designate one member to hand the quiz in. I just need the answers though in 6 and 7 the details are part of the answer. . Make sure the names of all group members appear on the answer sheet. Due by June 20, midnight. 1) Assume the value of a car is a linear function of time. When new the car is worth \$15,000; 20 years later the car is worth \$1,500.
