Discuss the results of your work and/or any lingering questions with your teacher.Choosing a Valuable CoinAlex collects coins that appreciate (increase in) value. At the store he has found three coins that he likes and can afford. Help Alex decide which coin tobuy by selecting two coins and comparing their values over time.1. Which two coins are you going to compare? Circle the two coins you picked.Coin ACoin BCoin CFinding Equations for the Values2. What are the current values and appreciation rates of the two coins you selected? (2 points:1 point for each of 2 coins)CoinCurrent ValueAnnual Appreciation RateA257B40 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)t, where V(t5
