1.2.4 Practice: Modeling: Exponential Functions Practice Mathematics for College Readiness Sem 2 Points Possible: 20 Name:Joshua Lee Date: YOUR ASSIGNMENT: Valuable Coins In this assignment, you may work alone, with a partner, or in a small group. Discuss the results of your work and/or any lingering questions with your teacher. Choosing a Valuable Coin Alex 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 to buy 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 A Coin B Coin C Finding Equations for the Values 2. What are the current values and appreciation rates of the two coins you selected? ( 2 points: 1 point for each of 2 coins) Coin Current Value Annual Appreciation Rate A 25$ 7%
B 40$ 5% 3. Write an exponential equation for each coin that will give the coin's value, V , at any time, t .
