1. Suppose a business purchases a photocopier for $12,000 in 2020. The accounting department of the business determines (from research) that the value of this machine after five years (in 2025) is estimated to be $8400. The business uses a linear depreciation model on all company assets (for accounting purposes). Define the variables: t= the time (in years) since 2020, and V= the value of the photocopier (a) Find an equation of the form V=mt + b that can be used to estimate the value of the photocopier over time. (Show all supporting work below and write your final equation in the blank provided.) EQUATION: Follow-up questions for this example: (b) State the slope value (with dimensional units) for this situation and interpret its meaning in context. (c) State the vertical intercept value (with dimensional units) for this situation and interpret its meaning.
