3. Write an exponential equation for each coin that will give the coin's value, V, at any time, t. Use the formula:
V(t) = P(1 + r)', where V(t) is the value of the coin in t years, P is the initial investment, and r is the
growth rate.
For each of the coins you selected, identify P and then set up an equation to find the value of
the coin at any t. (2 points: 1 point for each coin)
