Hey! I was wondering if I could get help with this question. a.) A new truck sells for $55,000 and depreciates at $-6,000 per year. Write a linear function of the form y=mx+b to represent the value of y of the vehicle x years after purchase. Use your formula to find the value of the truck 5 years after purchase.
b.) Suppose the truck from the previous question, retained 60% of its value every year, find the value of the truck after 5 years. Give an explanation for the difference in the answers to this question and the previous.
