Answer:

  • y = -6500x +55000
  • $22,500 after 5 years

Step-by-step explanation:

In the formula ...

  y = mx + b

the value of m is the change per year, and the value of b is the initial value. Using the given information, the equation is ...

  y = -6500x +55000

__

When x=5, the value is ...

  y = -6500(5) +55000 = -32500 +55000 = 22500

The value of the truck after 5 years is $22,500.
