Choosing a Valuable CoinAlex collects coins that appreciate (increase in) value. At the store he has found three coins thathe likes and can afford. Help Alex decide which coin to buy by selecting two coins and comparing their values over time.1. Which two coins are you going to compare?

Usethe formula:V(t) = P(1 + r)t, where V(t) is the value of the coin in tyears, Pis the initial investment, and ris thegrowth rate.
For each of the coins you selected, identify Pand r, then set up an equation to find the value of the coin at any t. (2 points:1 point for each coin)CoinPrFunctiona25%7V(t) = 25(1+7)^t40%5V(t) = 40(1+5)^t
