Recall the in-class problem scenario from In-Class Activity 8.C. Your work in that activity may help with this modified version. Part A: Write an equation to represent 8, the balance in an account after t years, with an initial investment of $1,000 with an interest rate of 3%, compounded each year. Part B: Create a graph of the compound interest model. (Use a spreadsheet, graphing calculator,or other graphing utility, or sketch by hand.) Use a time scale that runs from 0 to 40 years. Choose the best description of the graph below and bring a copy of your graph to class. Select an answer ill Part : Use the equation to compute the balance after 30 years. $ Part D: Compare this amount ta the amount you computed in class when campounding 2% interest for 30 years. How much more total interest do you earn when compounding 3% instead of 2%? %
