# Connecting exponential graphs with contexts

## Problem

A computer is sold for a certain price and then its value changes exponentially over time.
The graph describes the computer's value (in dollars) over time (in years).
A graph with time, in years, on the horizontal axis and value, in dollars, on the vertical axis. A decreasing exponential function passes through the point (0, 500) and the point (1, 250).
What was the computer's initial price?
dollar sign
